I have met a lot of good technicians on the internet. It just so happens that there is a really special one in Houston. He is a member of this group, a member of the iATN, BimmerTG, and runs a really class Bosch Service Center.
His name is Michael Haven and his shop is in west Houston about at the convergence of I-10 and 610. When I bought my 97 540i on ebay I had it checked by his shop. He was right on the money on the car and I got a chance to see his shop when I flew in to pick up the car...Nice! The shop's name is MPH Automotive.
