ws6vert has a G35, and so does the Crossfire Kid. Cbrseadude, I'm sure if you PM'd either one, they would tell you how they compare to the Crossfire.
From everything I've read about them, they're really a nice car. But then, so is the Crossfire.
I believe the Crossfire is a better bargain, but the G35 is faster (than a Limited XF) and probably has a better resale value too. But the Crossfire is more unique.
It's good to have choices.
