Definatly not a comp G, however it is plausable to be a GTP. The 04-05 GTs got the horrible looking 16" rims. GTPs got 16 or 17" rims depending on the order.

FWIW, my room mate got an 04 GTP non comp G with the polished twisty 5 spokes, HUD, and 5 button DIC. Seems the only thing he is missing is the gears and struts.
