Out of the dealers I have been to, East Bay Mini service has been the best! I recently developed a stress fracture on the windshield. No impact points visible. After reading horror stories about dealer reluctance to replace under warrantee, I called a couple places. I chose East Bay because Concord has treated me like second class customer since day 2. (Day 1 I bought the car from them so they had to be nice). The service technician at East Bay did the "pen test" and said there was detent at the top which caused the crack. Bryan Malgradi, a service manager, said "There's no obvious impact damage. I'll warantee it."
Even provided me with a loaner for the day. Unlike other MINI dealerships, East Bay is not out to screw you.
I think any dealership you go to, you'll run into incompetent service technicians. Last time I went to MINI of Concord for an indicator replacement, I found an Xacto knife poised dangerously close to the wires leading to the Xenons. At East Bay I came back to find my A pillar was cracked when they replaced the windshield. But as long as the service managers are honest, they'll take care of you. I'm getting the A pillar replaced this weekend as well as some other small problems, and I know from now on I will only go to East Bay MINI, even if it means I have to be late for work that day.
Thanks again to Bryan and East Bay MINI!
