OP. I drive both.
Statements like V8's burn more fuel than V6's are inaccurate. There is not enough difference in REAL world fuel mileage to right home about, especially in stop and go city driving when the smaller motor has to pull the same weight vehicle. The factory advertise mileage numbers are a joke.
And as for insurance, the difference for mine is about 50 dollars per year. Yes the GT is about 50 dollars more, but it is also valued at about 10,000 more than the V6 car.
You are so right about the donkey statement. True enough the 3.7
V6 is a great motor. I like mine. But a 5.0 V8 it is not, and never will be. Anyone who believes differently is misinformed.
So,IMO if performance is your main objective, you will be much happier with a V8 GT.
Good luck with decision.
