Isn't thats the Razzi body kit?
Nope. The Razzi is different.
This was the Concept GXP trim they unveiled a few years ago. It was going to look like that and have a 3 valve version of the 3.9L Engine or something with 270hp. Never happened. Instead they switched the GTP to the 3.6L in 2007, then shat out the current GXP body kit and kept the same engine with 252hp that the 2007 GTP had.
