We have a VW Rabbit GTI with over 230,000 miles on it and it still runs like new.
Compression is within new specs and it never requires adding oil between changes.
Even the interior still looks good. We drove a new Golf TDI in Germany. Had the 6- speed manual transmission. It's quiet and comfortable. My only gripe was that the engine will not rev in as wide an rpm band as a gas engine will, but that's inherent in diesels and not a fault of VW, and is the reason for the 6-speed gearbox.
