I have an opportunity to pickup a '96 Passat Diesel wagon with the 5-speed trans. It was originally a V6 gas GLX, but was converted to a factory '96 VW Diesel engine a few years back. White with tan leather interior. The factory Diesel wagons had the small wheels and brakes. This car has the larger brakes, wheels, as well as more beeps and squeaks, so to speak. Owner claims 42 mpg highway. Picture is of a '99 and not the specific car in question. Anyone have any experiences with the '90s VW Diesels in general, and Passats specifically?
