Frequently asked questions

ABOUT OUR SERVICE
What is ADP?
Automotive Diagnostic Precision provides car repair, maintenance, and diagnostics at the convenience of your home or office for a fraction of the cost of shops. Our expert, highly rated mechanics provide services where summoned.
The service is not only convenient, but also more affordable. Since our mechanics are mobile, we have significantly lower overhead costs compared to auto shops. And as a national brand, we can negotiate better prices from auto parts vendors. We pass these savings on to you.
Through our website and mobile app, you can request quotes, book services, and access advice from expert mechanics. With your free online account, you can also view the maintenance schedule and track the service history of your car.
How does it work?
- Simply request a quote by providing your location, car, and services needed.
- In most cases, we will give you an instant quote. You will see the breakdown of labor fees and parts costs. If an instant price is not available, we will send you a quote within one business day, often sooner.
- You can book an appointment by selecting a time that is convenient for you. Mechanics are available 7 days a week, 7am to 9pm. You will be matched with a mechanic who has the necessary expertise to perform the work on your car. You can see reviews of the mechanic before you book. Only customers who have completed an appointment with us can write a review — this guarantees that all reviews are from real customers.
- Your mechanic will perform the service at the convenience of your location, given that you have 1) Site Permission for the work to be completed, if not your own property, 2) your car is parked in a driveway or parking lot away from traffic, 3) your car is cooled from driving and 4) your car is on a level surface.
- We bill your credit card only after the work is done. You can access your service report and receipt in your online account.
- All qualified services are backed by our 12-month / 12,000-mile (whichever comes first) warranty.
Do you do warranty work or collision damage repair?
If you have an extended warranty, we can work with your warranty provider. We currently do not work with OEM and do not offer any OE warranty services. We also do not provide any collision related repairs.
How do I save with ADP?
The way existing customers can enjoy discounted ADP services is through one of three Membership subscription selections which vary in discount percentages which also include free perks.
Why should I choose ADP?
- Life is too short to waste it at shops and dealers. Let our certified mechanics come to you.
- You’ll love the ease of online booking, payments, and service records. Our mobile app will make it even easier for you to deal with car issues on the go.
- As a network of mobile mechanics, we don’t have the overhead costs like shops and dealers. As a national brand, we can negotiate better pricing from parts vendors than your local garages.
- Total transparency will give you total trust: You can see mechanics’ work history, reviews, and ratings from car owners in your community, their certifications and more. You will also get a detailed price breakdown with labor and parts information (no hidden fees and no shady markups).
- You will love having your own personal mechanic: Unlike shops and dealers where you are always talking to a service manager, you will work directly with a mechanic who will answer all your questions and give you advice. The work is done right in front of your eyes. You can choose to see how the work is done or you can go about your life while the mechanic is working right outside.
Can a mechanic really fix my car at my location?
Yes! All maintenance and basic repairs can be done right in your driveway. Our certified mobile mechanics carry all the tools, scanners, and lifts to do most repairs at your home or office. We service several thousand cars every month, from simple jobs such as oil changes and replacing brakes to more complex repairs like replacing timing belts. If you meet our S.A.F.E. site requirements, you can use this extremely convenient service. Ensure your service site is S.A.F.E.:
Site Permission: The site’s owner must approve of the scheduled service(s)
Away from Traffic: Be parked in a driveway or parking lot.
Free from Heat: The engine must be cool, avoid driving an hour prior to your appointment.
Even Surface: Ensure your vehicle is on a hard, level surface.
What type of services can mobile mechanics provide?
Our mobile mechanics currently offer over 500 services, including brakes, belts, hoses, fluids, lights, sensors, check engine lights, no-start inspections, leaks, and much more. You can see the full list of services here:
Do you have a shop where I can bring my car?

PRICING
How can I get an estimate?
You can request an estimate online by selecting your location, car and services. In most cases, we will give you a price instantly. You will see the breakdown of labor fees and parts costs. There will never be any surprises or hidden costs. If an instant price is not available, we will send you a quote within 24 hours, usually sooner.
How is the price calculated?
Manufacturer Calculated repair times for every service and Membership Tier enabled discounts of different levels which save you up to 35% off total labor cost.
What is your hourly rate?
Please refer to our membership Tier selection chart and compare the non-member labor rates and fees.
Is it more expensive than going to shops and dealers?
As a network of mobile mechanics, we don’t have overhead costs like shops and dealers, which in turn saves you money whether you take advantage of one of three membership tier options or not. However, our members do get the best bang for their buck.
Is there an additional fee for the mechanic to come to my location?
Yes, we charge a travel fee for non-members and members as well but at a discounted price determined by the Tier level to which they have subscribed.
Is there a cancellation fee?
We would appreciate as much notice as possible if you need to change an appointment. It’s free to cancel more than 48 hours prior to your appointment. If you cancel within 48 hours of an appointment, you will be charged a $75.00 cancellation Fee. If you cancel within 12 hours of an appointment, you will be charged a $150.00 Late Cancellation Fee.
Am I supposed to tip the mechanic?
Our mechanics do not expect a tip of any kind. Instead of leaving a tip, please recommend the mechanic to all your friends. You may also want to write a review on their profile and rate us on Yelp.
What if the mechanic finds that my car needs more or less services than I had requested?
You’re always in control. If our mechanic finds your car doesn’t need all the services you requested, we’ll remove those unneeded services and lower your bill, right on the spot. If your car needs additional repair services, our mechanic will provide you with an itemized list of what you need. You can decide to accept or decline those additional services.
Is there a fee for mechanic to diagnose my car?
Yes. We charge a diagnostic fee to come to you and diagnose your car. This fee covers the inspection and diagnostic time and cost of driving to you. Diagnostic fees start at $100, regular rate for non-members and may vary by market. Start a quote to understand pricing in your area- there’s no commitment until you confirm an appointment!
What does the diagnostic service include?
If your car has a problem, you can book a mechanic to perform a diagnostic. A mechanic will come to your location and inspect your car. Our mechanics go through a step-by-step process to rule out or confirm any part(s) failures. Diagnosing a problem is a process. Sometimes the only way to prove that a part is defective is to replace it and recheck the car. Your mechanic will diagnose the car and then provide preliminary recommendations and repair estimates, based on their visual inspection and any tests performed. The inspection report may include photos, test results, audio notes, recommended services, and a service estimate (if applicable).
Does ADP offer discounts or coupons?
The way existing customers can enjoy discounted ADP services is through one of three Membership Tier selections which vary in discount percentages.
MECHANICS
How do mechanics work with ADP?
ADP is a network of expert mobile mechanics. Independent mechanics apply to join our network. Every mechanic goes through an extensive screening process that includes background, criminal, and reference checks. Once approved, mechanics are booked for jobs through ADP.
Your service agreement is with ADP, not the individual mechanic. Although you are provided with the service by the mechanics in our network, we stand behind the service with our 12-month, 12,000-mile warranty.
How are the mechanics screened?
Mechanics are screened through a two-step process:
Step 1: We perform a background check, skills check, and one-on-one interview with the mechanic. About 5-10% of the mechanics who apply are approved.
Most of our mechanics are certified by ASE (National Institute for Automotive Service Excellence). Some of our mechanics are certified by similar organizations and/or have dealer or factory training. You can see mechanics’ certifications on their profile online, which is accessible during the booking process. You can also review their experience, work history, jobs completed for other car owners, fees paid by other car owners, and real customers’ ratings and reviews. We take pride in being totally transparent.

You can also review their experience, work history, jobs completed for other car owners, fees paid by other car owners, and real customers’ ratings and reviews.

How do I get a mechanic who specializes in my car (Honda, Ford, BMW etc.)?
ADP matches you only with a mechanic who is qualified to work on your car. Many of our mechanics have dealer or factory training with certain brands. Some of them have years of experience working on certain types of cars (e.g. German cars, domestic cars, etc.).


SCHEDULING
I don’t know what’s wrong with my car. What can I do?
You can book an appointment for a mechanic to come out to you and inspect your car. They will provide their inspection report and recommend services that your car needs.
How can I book an appointment?
You can book an appointment online submitting your location, car, and services. In most cases, we will give you a price instantly. You will see the breakdown of labor fees and parts cost. You will also see the list of available times. To book an appointment, simply select a time that works for you and provide your location and payment information. We do not bill your card until the service is complete.
Why is a credit card required to book an appointment?
Your credit card is not billed until the mechanic has performed all the services. However, a valid credit card is required to hold your appointment and to verify that the appointment request is legitimate. This prevents people from making fictitious appointments and ensures that mechanics are not wasting their time driving around. We use bank-level security, and all your data is passed over a secured 256-bit encrypted connection.
Can I choose a mechanic?
You can choose the same mechanic if you have used the service before. If you are a new customer, we assign you a mechanic who is qualified to work on your car.
How soon can I get a mechanic?
We have mechanics available 7 days a week from 7am to 9pm. Depending on the availability of parts, we are usually able to provide services the same day or next day, though the mechanics tend to get booked rather quickly. You can see mechanics’ availability after you request a quote.
How late can I cancel an appointment?
We request that you cancel your appointment more than 48 hours prior to your appointment’s start time. If you cancel less than 48 hours before your appointment, you will be charged a $75.00 cancellation fee. If you must cancel less than 12 hours before your appointment, you will be charged a $150.00 late cancellation fee. You can cancel your appointment using your online account or by calling us at 1-111-111-1111.
How late can I reschedule an appointment?
We request that you reschedule your appointment more than 48 hours prior to your appointment start time. If you reschedule less than 48 hours before your appointment, you will be charged a $25 rescheduling fee. You can reschedule your appointment though your online account or by calling us at 1-111-111-1111
How can I reschedule an appointment?
You can reschedule your appointment using your online account or by calling us at 1-111-111-1111
What if the mechanic is late?
Please remember to allow 30 minutes for your mechanic to arrive. Sometimes mechanics get caught in traffic or a previous job takes longer than expected. We do apologize if this is the case. If you have not heard from your mechanic by your appointment time, please give us a call 1-111-111-1111 and we will work to resolve the issue. If you need to reschedule, we will take care of this for you as well.
PARTS
How do I know the parts are of good quality?
We at ADP have undergone a rigorous filtering process to select the brands that are best suited for your car. Our parts catalog has a list of approved brands for each type of car and each type of part. We take pride in having a network of mechanics that uses high-quality parts. Whenever possible, the parts used are OE parts or aftermarket parts that meet or exceed OEM service specifications. When reviewing your quote, you will see the brands of the parts. Each part is clearly marked as OE, OE equivalent or aftermarket.
Do you ever use Remanufactured or used parts?
We don’t engage in the business of supplying or installing used parts. Only in very rare cases do the mechanics in our network ever use remanufactured parts — usually in older cars where the parts manufacturers have discontinued the production of new parts. In those rare cases, the parts will be clearly marked as “remanufactured” on your quote.
Can you help me find parts from junkyards or auto-recyclers?
We apologize, but we don’t engage in the business of sourcing parts from junkyards or auto-recyclers. In most cases, we prefer not to install parts that are used or sourced from junkyards due to liability issues.
Where are the parts coming from?
We buy parts from several vendors — from local vendors to wholesale suppliers across the nation, allowing you to receive high-quality parts at reasonable prices. Currently there are over 100 warehouses nationwide that ship parts directly to our mechanics. Whenever possible, we prefer OEM (original equipment manufacturer) or OE-equivalent parts, and we think they’re better for your car. We also offer high-quality after-market parts, often from the same manufacturer as the original parts.
Can I provide my own parts?
Yes, you are welcome to buy your own parts and book one of our mechanics to install them. When reviewing your quote online, open the “price breakdown” tab, and click on “parts options.” From there, you can choose to remove all the parts from your quote. Please take into account that when you provide your own parts, our service warranty is voided.


WARRANTY
Do you carry proper liability insurance?
Yes. ADP carries commercial general liability insurance for services performed by the mechanics in our network.
How can I file a claim under this warranty?
To inquire about obtaining service under this Limited Warranty (if applicable), email us at automotivediagnosticprecision.com/contact-us or call us at
What is the warranty on labor and parts?
We stand behind the workmanship and parts provided by mechanics on our platform. Every service booked through ADP comes with our 12-month / 12,000-mile (whichever comes first) warranty, measured from the date the services are provided and the odometer reading shown on the applicable invoice.
