Visit Acurazine.com before you pull the trigger. I had an 07 TL-S in the past (same as the 08). If you get one, STAY AWAY from the manual trans. The 6-speed has a weak 3rd gear that a lot of people have had to replace - on their own dime. Acura tried to tell me it would be $3k to fix the problem while the car was under warranty!! What a joke. No problems reported on the auto trans, though.
I've also had Evo VIII an IX. No problems there. Buying used is tough to find an unmolested one, though. 335- they just upped the warranty on the stock turbos to 8 years/80k miles and HPFP is 10 years/120k miles. So, a little peace of mind there. Good luck with your search.
