My nieghbor has an 04 Cobra, with 7K on it, Looks like it just came off the show room floor and it's a nasty mofo. Smaller pully, CAI, full exhaust with O/R X pipe, custom tune, stagered setup with drag radials. He said it's putting down aroung 450whp, forget what the torque was. Nice to have the IRS too.
Road with him once, very comfortable seats, that you get slammed back into banging through the gears
If you are just going to drive it on the weekend, I say get it, like was already said, they are rare and could be worth alot more someday, and should be kept in the garage.
If your going DD, then do the GT
