When it comes to FAST, STI's have garbage drivelines, they break all the time. Pick the car you like the best and fits your individual needs. As far as fast, thats debatable.

I would say a great companion car to the HHR is a Solstice/Sky. You get the great ecotec engine, RWD, convertible, beautiful lines, not too expensive, and they are IMO going to be collectable someday.
