I live in the hilly contryside of the Oregon coast and my TDI Jetta is a pleasure to own and drive. It is reliable and gets 45-48 mpg on my daily 90 mile commute. It has plenty of pick up and low-end torque and handles great through hills and in wet and light snow. I have never had a problem with it in two years and 50,000 miles of ownership.
I love the tight and smooth build. It is very quiet for small sedan. It has a decent sound system, comfy front seating, and a suprisingly large trunk.
The cup holders stink. Tthe rear seats could use another 1.5 inches of leg room. VW needs to bless some third party synthetic oil so I don't have to fork over $100 10,000 miles to the dealer for an oil change.
