I have an 04 HCH CVT with 50k miles on it. I bought it 18 months ago with 14 on it and i have only done regular preventative maintenance. The only problem I've had, which isn't fixed yet, is the passenger window doesn't roll down all the way because of some sort of obstruction inside the door panel. I have just not gotten around to fixing that. Otherwise it's a great car. The CVT is really cool. I am a Manual-only kind of guy, but the CVT doesn't have the annoyances that bothered me about traditional automatics, so I love the CVT. I find myself getting annoyed by the smaller things, design decisions that I would have done differently, but that's personal preference mostly.

Buy it, drive it, love it, and feel good about it. That's my advice.
