VW's suck. They still have timing belts when nearly everyone else have gone to chains. It cost @$1k to do the belt every 100k miles.
Our 2010 Jetta TDI quit running when my wife was pulling out onto a busy highway. It was 5:30 AM on the coldest day in Feb. -6 Degs F with a wind. Luckily she was able to coast to the underpass and no truck was coming. VW only covered $300 for the repair. Did I mention they suck.
Our 2002 TDI would die randomly. Have you ever been in a car that quits where ever. It is rather frighting. VW dealer said they couldn't find the problem. So I did the lemon law thing on them. They finally replace the instrument panel and that fixed it.
VW's have been the most unreliable cars that we have ever owned. I like how they ride and the features of the cars but they suck. And like the guy above M-B's aren't much better. My 911 has been very reliable
