First - thanks to this board, I trolled for about 2 weeks reading up on the cars before I dove in. I ended up with an 04 Quicksilver / black int M6.
I love the T56 and other than some rims, it's stock. I'll probably add a CAI, cat backs and shifter and call it done. (Maybe a 100 shot kit this summer though.

)
I used to have Grand Nationals and really consider the GTO the GN of the new millenia. I still have GN blood in me though, my drag car is powered by a Turbo Buick V6 but the only real GN part on it is the intake (which is a shadow of what it used to be.) Here's an old video of it someone made at a Camaro club track rental. It'll go 8's this summer for sure, it went 155 last year.

Between me and my (2) boys, we also have a Jr. Dragster and (4) dirtbikes, one is a YZ426 SuperMoto (and is nitrous'd).
Just wanted to say howdy from wintery IL and share my excitement about the car. I drove 400 miles yesterday in blustery winter weather to go get it and then had a nice cruise back home. What a car, my wife and kids love it as much as I do.
