I'm new to the forum, and to VW ownership, but I have to admit that I'm amused by how much the folks on the board here are worried about Civic Si's. It looks downright like a complex.
You'll never see me disrespect Hondas. They are great cars, and I've owned and loved driving a few (Integra, Prelude, Civic). Never had a single problem with one of the three over the course of 14 years, which is awesome.
I traded in a 2005 Nissan Z because it broke down on me three times in the 18 months that I owned it. Chances are, I'll never own another Nissan.
Traded the Z for a 2007 GTI Mk V. and I imagine it'll land somewhere between the Honda and the Nissan in reliability. In my mind, the car has less to do with the driving experience than the driver, e.g. your technique, outlook, etc.
