If anyone is from the Marietta, GA area and/or took your German auto to Performance Plus Hi-Line give me a shout! Unfortunately, the shop closed some time ago as the owner, Christopher Bello, commited suicide in mid 2001. He taught me a great deal about BMW mechanics and my Brother handled schooling me on Mercedes. Chris was quite a fellow, a gearhead to his core, an excellent boss, and just a great guy!
