You are now officially defined GAY.
It's the same car but with FOUR doors. If the GTO was a FAIL (it was sales wise), the G8 is a super fail. GTO, G8, Catera are all the same car with different plastic and crap. If you have to choose, at least get the ONE with two doors.
I'll take a silver 2006 GTO with red interior and M6, thanks.
