I saw that last night. Very nice car and work. I was very impressed with the overall effort. The one thing I cannot figure out is how it is even usable unless you are driving on drag radials all day

which even then the car is not set up for that kind of power delivery(meaning drag suspenson and such) Seem like a nice toy though. My Dad has a 2006 C6 with 490 HP and it's a monster I can only imagine what the GT TT is like. He used to have a Callaway TT Vette in the late 80's and that was a monster as well.
