I had a used VW diesel Jetta. It had over 180k miles on it (bought it with 105k) and it stil got 52 mpg. Almost no maintenance. Can’t recommend aone of the VW TDI diesels strongly enough. Only sold it because I was going out of the country for a couple years.
We had an 02 TDI and it was very unreliable and expensive. Also uncomfortable on a trip. We dumped it with glee and will never go VW again.
