Great vehicle, but with an automatic transmission it's a gas hog. My average highway mileage is only 28.8 MPG. I've had a few tanks in the low 30's MPG. The city mileage is around 20 MPG. I've had it checked by a garage twice and they didn't find anything wrong. Had it into a VW dealer once for another problem and the representative didn't think that 28.8 MPG for highway mileage for an automatic was out of line.
Vehicle is really great and flexable. No one favorite feature.
The Golf 4 is out of production so it's a moot point.
