The only complaint I have is that it rattles, and Toyota has not fixed the rattle. Intermittent, of course, sounds like the hatchback or the sun roof. I love this car. I love the way it reponds at 60 to 70 mph, I love to put it through hard corners, I love the manual transmission. People over 6 foot 3 have a hard time with the head room, but it fits me fine. I look forward to driving it.
Drivability - you step on it, and it goes in the direction you point it, with authority. It makes me want a few more horses, but honestly they are not needed. I have not had a car I have liked more. I would like a new one.
Include a hybrid model - put the Prius Synergy in this car - gomers like me would love it. If one were going to redesign, figure out a way to get more headroom, front and back. Tighten down anything that rattles. Get a radio with easier controls. The new ones may have them on the steering wheel.
