When I bought my '88 RX7 14 years ago the previous owner told me that he got all of the servicing done at PR Motorsports, so I tried them. The drive to Hayward from Oakland isn't quick, but unlike almost every other car shop that I have been to, Rick and his crew seem genuinely interested in my long-term interests. Hey has always given me a heads-up on parts of the car that I should watch out for in the future and gives me the option of when (or if) to do the repairs.
Pros: like family, really know their stuff, won't try to do repairs you don't need
Cons: Far from Oakland, but worth the drive
