Why buy the V6 to spend a bunch of money to get it to the GT's performance when you can get the V8 the first time, having the better and more powerful engine as well as better suspension and overall setup. Then spend money on it to get better performance, which would take beyond more money that it's worth to get the V6 to that level (which in most cases isn't possible anyways). The only advantage to a V6 is maybe better gas mileage and lower insurance. Those are the ONLY advantages. You say price? True, but go get a Fox body 87-93 5.0 for a few thousand. Better and cheaper than a newer V6, eh? Even low mileage 5.0s are out there and cheaper. Usually cheaper insurance as well.
