That's what a lot of people over here drive. Of course, this is because gas is about $4.85/ gallon.
When I drove to Munich, I had a Passat TDI and I was really impressed with the drivability and power it had. Not a GN, but still fun to drive... even has a turbo whistle. 140 mph on the autobahn too. Also drove a Golf TDI on the autobahn... did about 125. Not bad. If I was staying here, I'd buy one.
