I've been going to European Motors for 3 years now for my 2003 BMW z4 (not purchased from European Motors).
I thought I'd put my two cents out there, based on my interactions with Uwe and Gabriel.
My car has had it's brakes, Coolant hose, and Wiper Relay fixed in the last 3 years after my BMW Factory Warranty ended. And each time I come in Uwe is always friendly, clear and patient. His shop does good work, and the cost for work completed is always great and oftentimes lower than other quotes I've had.
If I ever had any question about anything, I always ask and Uwe or Gabrielle tells me in detail what has been done, and any suggested work to keep my car in great shape.
I will keep going to European motors for all of my Service needs.
