    I called C.A.R.S. and the guys were so upfront and honest. They quoted a price and a time frame and kept both! I honestly couldn't be happier with this place. Talked to them about getting some after market stuff done to my car and will definitely coming to talk to these guys first!

    Sean and Cameron were great! I had my vehicle taken to other shops that couldn't diagnose a check engine light. After spending over 1100 dollars in repairs, Cameron and Sean were able to repair the car and also show me the part that was bad. They are very honest and helpful. I recommend their shop for anyone that's looking for honest reliable repairs. Thanks guys for your honest service.

    Cameron the front desk gentleman is very nice and knowledgeable. Yesterday I went in with car troubles and picked my car up today! Their service is so fast, honest, and reliable. The price was very affordable. They made my first experience with them great. I’ll definitely bring my car back for more car repairs in the future if needed.

    Best automotive shop in Northern Virginia! It's not an easy task to find a honest, good and reliable shop. I stumbled onto C.A.R.S about a year and half ago when my Subaru had been worked on by another shop and who made things worse. Cameron and the crew at C.A.R.S. fixed the preceding shop's poor work and charged an unbelievably (low-fair) price. I have taken my Subaru back in there for other work and every time I am blown away at how good, honest and fair they are. I don't write reviews, ever... but these guys deserve all the praise I can offer.

    Brian worked on my audi a6, which was consuming a lot of oil. He did a thorough job working to resolve this issue. Not only was he thorough, but he was also very honest and very fair with his pricing. He and Jerry, a nice member of his team, communicated in advance what needed to be done and provided me with an accurate quote. I highly recommend Brian and his team at My Dad's Automotive. They are skilled, trustworthy, and fair in pricing.

    Thorough, timely and reasonable rates. New ownership as of 2017 is terrific! It's worth the short trek over from Falls Church for all my cars! From Ram, to Mazda, to BMW, they all come here.

  • Michael Towery9 months ago

    I plan to use this shop for all my future auto services and repairs. I have tried many other well-rated repair shops in the area over the years, but I've had the best experience with CARS. Their customer service is great, they made proper diagnoses and provided sound advice, the services and repairs were timely, and their pricing is clear and fair. I'm thankful this shop was recommended to me by a friend and will be similarly recommending CARS to others.

    This is a great BMW repair shop with two automotive enthusiasts in Sean and Cameron. They have maintained and tuned my 2000 BMW 750IL, from intake leaks, to suspension, to EKAT problems, from routine to extraordinary they have totally impressed me with their expertise. They also maintain my 2016 750i. In six states and 15 years of BMW ownership this the best Indy BMW shop. My highest recommendation--the best value and service of any BMW service firm in Northern VA, DC and Maryland.

    I had my BMW X5 in for service at Chantilly Auto Repair Service due to a major oil leak and broken hatch opener.

    Their team was very easy to deal with and was understanding of my tight timeline for repairs. I was given a free second opinion on the repairs quoted from the dealer and they were even willing to perform a software update at a fraction of the cost.

    I was very happy to have my car repaired and back on the road quicker then I expected. Also the total repair cost was much much lower than the dealer.
