I'm prob ganna test drive both in a few weeks I'm not buying a new one prob be a 2003 you can find them pretty cheap around 25 and low milage. the thing is I can't find a manual G-35 but there an ass load of Z's to choose from. probly be buying either by late May. As far as moding goes its over $5000 to put the twin turbo in either..... and thats the 1st thing I wanna do to which ever one I choose.
