I have a jetta diesel. I get the greatest gas mileage and have not had any problems. On ANY car you buy, buy all the extended warranty you can, its like life insurance.
I love my car so much, sun roof, cruise control, 8 speakers, great stereo, etc, etc, all come STANDARD!! Ifg my car died today, I would buy another jetta diesel in a heartbeat. It handles great and has disc brakes too...everything is standard!
