While I can't be sure they are as good as it gets - I think they are darn good.
I drive an 06 BMW 330i, manual transmission, 70k miles. Not too many shops here in town that are able to properly work on BMW's and run the correct diagnostics. This shop does.
Staff is friendly and courteous and the mechanic is spot on. Often the mechanic will personally give a run down of what was done and will answer any questions. (I always want details)
The original quotes are well under dealership prices (as would be expected) and they ALWAYS breakdown the pricing of the quote. On two separate occasions they came in under the quoted price.
After bad experiences (read: expensive mistakes) at other shops in town, I will not go anywhere else.
