Contact Us“They just did complete new rear brakes and rotors on a BMW X2 — $640.00 for a family member I referred! At a dealership this cost would've been double that. All new factory BMW parts and it was all done as a waiter after a couple hours. We thank you.”

“First time customer. My BMW i3 was having some AC issues. I searched the web for nearby BMW specialists. This place popped up with tons of experience. Randy was awesome! Took the extra time to explain possible issues and solutions. Definitely didn't feel pressured. Way better vibe here than at a dealership.”

Yelp Review
“I was recommended to BA from an existing client back when Rob's dad Manfried also ran the shop. In all of these years I haven't had one complaint with the service at BA. The service is efficient and straightforward. I appreciate knowing that I have a reliable professional to call when I have a problem with my car. A few weeks ago my car started to overheat and shut down. I towed my car to Rob late in the afternoon. He diagnosed the issue as my water pump, ordered the part, repaired the car and performed a routine service by lunch the next day. He knows what he is doing and I appreciate it. I don't have to worry about exorbitant fees or games and tricks that I've experienced at the dealerships. I recently told Rob that when he retires... I will stop driving BMWs.”

“I've been taking my 2007 335i here for service ever since the 4-year warranty expired. Rob, the owner and mechanic, is certified and does excellent work. He is very knowledgeable, fast, reliable, and honest. Over the years I've had to use the dealer for recall notices — they always gave me a list of things that 'needed' to be done. I always took the list to Rob, who explained what was actually necessary. He's saved me lots of money and I trust him. I've referred friends that own BMWs and they too have been extremely satisfied.”
