For the few here who own tC's, or know people with them, does anyone know if there are any problems with them considering that it's a new model (versus the xA/ist and xB/bB, which are merely rebadged)? I've been trying to find problems online, and I haven't found much (it is really new, after all), save for something about a moonroof rattle which is easily fixed at the dealer by tightening some loose screws. Obviously I'm pleased to here about no problems, but at the same time, I worry that they will begin to crop up. Any thoughts?
