I have a '98 Jetta Tdi that I bought brand new. I have 222k miles on it so far and it has been the best car I ever owned. I get over 50mpg on the highway. However, parts are insane expensive and I cant hardly work on it. Feels like it has 3x the power of my '79 300 D and gets far better mileage and much more comfortable.
But I drive the '79 and the wife drives the Jetta. Given the choice I would take the benz because parts are cheap and I can fix anything on it that goes wrong.
I guess I am just stuck in the 70's.
