My 04 TDi Jetta, automatic is approaching 80,000 miles. Runs perfect, never any problems. I am trying to decide to trade for a new Jetta or keep mine. If I keep it, I will try to make 200,000 miles and junk it. How long do trannys go? How long do engines go? I still get around 50 mpg. I understand the new Jettas are barely getting 40. Cost of the new Jetta is a deterrant, may cause me to look at other cars. Whadda ya thinkl?
