I also thought so. but the Jetta/Golf 4 are crap. I used to own one.
Don't leave the keys in the car, it's got a tendency to lock itself. Even if the car is started.
Your battery will last just more than a year, if your lucky. At some stage after replacing your brake pads, the brakes will start locking up. This will heat up the disks and warp them. VW has no clue how to fix this. We replaces Calipers, Brake Master Cylinder and eventually the ABS pump. It's better now. There was one on the VW floor where they replaced the whole braking system and it still had the same issue. Alternator pulley will fail breaking the pulley off.
The engine lost a cam lobe and bend a few valves leaving the head completely damaged.
The ABS and engine problem happened after I sold it.
I sold it and bought a 4.6 Range Rover HSE Vogue. It's to this day still cheaper to run than the TDi Jetta.
Edit:
That being said, that engine has a lot of torque that's a pleasure to drive in a hilly road. When the car running fine, it was not all that bad.
