Get an 08 or 09. The TC models are so easy and cheap to mod. Not to mention they put out monster torque. Stock they put down 250+WHP and 250+FTLbs. And stock there are people running 13.6's in the 1/4. Fastest I got mine was 13.71 in San antonio, and mine is 99% stock. Just got a muffler delete and K&N drop in.
