Jettas were junk and still are.
How so vis a vis any other vehicles?
I had a 2004 Jetta 1.8T. That thing was fun to drive.
Did have to replace the engine which I think was because the oil changes were never with the recommended synthetic oil.
We bought a used Jetta for our teens to drive when they got their licenses. Bought it in 2002 and it was probably three or four years old. That thing gulped a quart of oil with every gasoline fill-up! I hammered the kids to add oil at every stop at a gas station. Surprisingly, it never fouled the plugs. That was the one and only Jetta we ever owned.
Our experiences with two Volvo 740s were just as bad (not oil, though) and a horrible experience the past six months with a Ford Escape.
