I'm new to the TDI world, and can't wait to get one. Most likely i'm looking for a Jetta under 80xxx. 99.5-2004 (I know about the vnt but not alot) I know a few things about them IE. Making sure what mileage timing belt it has and if it has been replaced, who did it. What type of oil was used. So basically, I need to know what year engines/cars were better than others. Can anyone help me? I greatly appreciate it.
