Unfortunately, Dave isn't doing any maintenance and/or parts anymore. He's strictly in the wholesale parts side of things, and works on the 2 or 3 race-car teams he's sponsoring.
He's also gone back to working as a service advisor for Pfaff...
I'd suggest Bavarian Motors as Rob has...then again, I'm a little biased.
I'm not really an asshole, I just play one on the Internet
