my 07 has 55k miles already and still rolling strong. I would look for after market products (could mean more wear and tear on the car cause they are driving ti hard), I would look at the previous owner (young, old, etc...). Try to find a GT model. Leather, LED's, HID's, bose stereo. Those should be comparable to the base sport model.
You will undoubtedly have chips in the paint...the paint is not that great. I have multiple chips due to that...shit, my car got egged and that caused many paint chips from the shell.
I don't have any other issues...transmissions and clutch still running great, suspension is awesome, everything still functions. When you take it for a test drive keep away from the turbo and if you find a hill and are going around 45-50 in 5th or 6th gear, floor it and see how the turbo reacts...mine sometimes rattles but comes right back on...hard and STRONG!
