My friend Ken has said that his 997 GT3 RS is the only GT3 he'd get, as he prefers the wider rear end... it is more muscular.
my personal opinion? The green would fit in the same soul as the Hulk you parted ways with.
How is your epxerience in harsh track oreinted street cars? Is it the look and feel of the GT3 that gets your blood pumping? In the US, the RS ought to hold it's value quite well for a while, so I don't think that will be an issue... where the Turbo, and normal GT3 will drop off more quickly.
The US speced car has more comfortable seats, and A/C as standard equipment, and not the intrusive roll cage (full cage) as the european counterpart. I would fully expect the GT3 to ride about the same quality as a Z06, perhaps a little harsher.
In any case, for myself, I would love one .... [/selfishthoughts]
