I know people with late 90s New Beetles and people with early 90s Jettas. It seems that the quality of VWs has become hit or miss in recent years. I am curious, though, if beyond the cars themselves the TDI drivetrains are, like any worthwhile diesel, 300k motors. I ask because I am starting a company that is going to build custom bio-diesel and grease cars. Mercedes motors are, obviously, very expensive. A TDI, however, is a lot less expensive and has been proven capable of moving around a 3200 lb (I think) Passat. A lot of really cool old cars weigh less than 3200 lbs, so, it all boils down to whether or not the TDI is a viable candidate for such a transplant. What are people's experience with the motor (and transmission) itself?
