I drive a Mini Cooper S JCW. The dealers are known for overcharging - and you don't get what you pay for.I discovered Roy and Beyer Motor Works a while back. They did an excellent job replacing my clutch and installing a limited slip diff. And just recently they helped me track down an extremely elusive issue with my car. It's during this fault-finding mission that they gained a lot of respect from me...they had ample opportunity to exploit the situation (and just go on a parts-replacement spree) but they never did...they always kept me informed of what was going on, and on what they will try next. They took the issue extremely seriously and gave it a lot more TLC than a dealer would have. The issue was resolved, and frankly I'm impressed with the very realistic invoice they gave me for parts&labor.
