I am in the same boat, sort of. I'm currently driving a 1985 Audi 4000 Quattro, with about 180 zillion miles on it. Currently the driver's side door panel is off because I just replaced the regulator, and I can't tell if this one is working any better than the old one. I will continue to shoe-string this car until the "S", with my name on it, arrives. Right now it's all about spending no money on the Oldi and putting away a huge down payment on the "S"!
