You can check my BOSCH Service Center, Woodlawn Motors. Lincon Drive, off of Chelten Ave. Pretty easy to get to Any BOSCH Center is a great place for Euro cars, there is one across from the old IKEA near the Turnpike. Woodlawn is very popular with AudiWorld guys, the owner John happens to be a personal friend and very reputable. Do a quick search on AudiWorld, you will see many positive responses. 800-843-5939 Otherwise, there is a guy, Ron Ginona near Ardmore, good shop. Yeah, well Woodlawn is the best of the best, many Porsche Cup racers there for corner-balancing and custom engines. I've been to Watkins Glenn with the guys for Porsche Club and everyone seemed to know him. Several Speed GT cars there too.
