Great TDI fuel economy: approaches 40 mpg in city and have registered 55+ highway under the right conditions.
Despite not being power seats, both driver and passenger seats adjust vertically to accommodate taller drivers. Lots of head room as a result.
Diesel reliability and longevity. Gotten nearly 5 years out of the car without any of the stereotypical VW glitches.
Awesome low end torque and turbo performance. Very quick below 45mph.
