I'm located up in lebanon ohio, and yes its hard to find a trustworthy mechanic to wrench on my vovo's... i try to do all the maintenance myself, but have been meaning to give the new dealership down on union center a try.... as for the problematic cars your looking for my last car, a 1990 760 turbo is currently sitting in the lot at one of my mechanics... if your interested in it the only thing i think is wrong with it not causing it to run is a fuel relay, if not im going to scrap her.
