Lets just say, I need to stop driving my friends cars. A VW obsessed friend with a 2003 Passat just added a 2002 Jetta GLS with the 1.8T. Wow, for a little 4 cylinder it gets up and goes. How is reliability among the 1999-2005 1.8T models? I know timing belts cost a fair amount of $$$, but otherwise, what are we looking at? Thanks!
