I own a 2003 BMW 325i that I bought from BMW Nashville. Greg has been working on my vehicle since 2007 and no one else touches this car. I moved to Wisconsin in 2010 but drive annually to TN for my maintenance. The BMW Madison dealership will never touch this vehicle. With 219k miles on the odometer, I came to ADR for a refresh and to add some power. Greg had to put down over 30 hours to finish all my work. He installed headers, an AFE intake, a Dinan throttle booster (freakish response) , and then he downloaded the appropriate ECU tune. I got a new cooling system and a new power steering pump. No small job. The result on the power? My acceleration lag is gone, the engine breathes and expels exhaust with incredible sound, and it shifts and pulls hard throughout every gear. Call it smooth as silk, smooth as glass, or smooth as butter, I really can't decide. If you're like me, and don't want to give up on your 325, 328, or 330, because you love it but need more speed -- go to ADR and discuss some upgrades. Thanks for all the hard work Greg! You never cease to amaze! Update: 11.21.23 - Sitting at a stop light I got behind a 435i to taunt him. Chased it up a ramp and was side by side at 60mph. It pulled away but I closed the distance and by 110 mph our cars were side by side. My Dinan boost was at 175% not even 200%. He got a look at my 325i badge. Pretty sure he wondered what the Hell happened. lolServices: Exhaust, Steering & suspension repair, Auto engine tuning, Air conditioning, Oil change

They always get me done right! I have brought my 2013 BMW 328ix to them multiple times and they have always found a way to fix it! They fixed my BUS module without having to even replace it. They fixed the shorts in it and got everything back right! If you have a BMW or any foreign car bring it to Greg! They are the most knowledgeable Euro shop around! BMW of Nashville recommended me to him if that says something!Services: Electrical repair, Exhaust, General repairs & maintenance, Auto engine diagnostic, Auto engine tuning, Engine repair, Auto maintenance

Well it was a long slog getting the Aston working properly, but Greg persevered and it's now back home! I really appreciate Greg's persistence in finding and dealing with the myriad of faults, most would have given up weeks ago. Thanks guys!

If you have a BMW and not using these guys service that s already your first mistake. They are passionate about their work and treat the car as if it was their own and do a phenomenal job to make sure your car runs as if it was brand new. This is the only place I ll be taking my cars to as with them I feels tons more confident about buying BMWs knowing I have them to work on it.Services: Tires, General repairs & maintenance, Auto engine diagnostic, Engine repair

Once again, ADR to the rescue! Our car was disabled and on the side of the road on a Sunday morning. Greg cheerfully met us at his business after offering to call a tow truck. This is just another example of how he goes above and beyond expected. His business is the whole package competent, honest, and concerned about making things right.Highly recommend.

I am very appreciative of the work that Greg and his team does. It is comforting to know that I have somebody that I can trust to fix and maintain my car. Greg is very knowledgeable and takes time to explain the problems and fixes for your car. I heard about his work through a friend and have never been dissatisfied since I started taking my car ro him 3 years ago.
