1) Rattles/noises - passenger door, glove box, sunroof, rear deck, above gauge pod.
2) Squeaky suspension in cold weather... it's ridiculously squeaky and sounds like it's riding on 20 year old suspension.
So far this car has proved to be problem free (has not broken down, has always started, even at -30*C). The car has a fairly comfortable ride considering the suspension setup. The performance is great for a front drive car, the handling is phenomenal for a front drive car as well, especially considering the torsion beam rear end. The seats are well supported, comfortable and very sporty. The clutch and transmission feels great.
Now for the bad:
This car is just not refined; maybe I'm expecting too much for a sport tuned econobox. The suspension is so noisy in cold weather it's embarrassing to drive. The interior has rattles galore, and different ones that show up at different temperatures. The engine feels rather rough at idle considering the technology in 4 cylinder engines today. The clutch and transmission like to clunk when shifting from first to second, and second to third, unless you're really gentle and slow on your shifts.
All in all, I will not call this a horrible car. I wanted a fast car for cheap, and that's what I got. As far as performance goes, this car rocks for the price paid, but as far as overall refinement goes, it's only at par with typical domestic small cars, which is not good.
If you're looking for a fast car for very little coin, this is the way to go. If you're as picky as I am, you will very quickly hate the car overall, as I did. Too bad the car is likely worth 5k+ less than what I paid already, 2 months later, otherwise I'd trade it for something else.
