I got the V6 for several reasons. I could have bought a GT if I wanted (my wife even gave me permission) but coming from a 320HP Trans
Am, the V6 seemed plenty for a daily driver and cruising, the mileage is much better (on regular gas) and upgrading to 3.31 gears gave me the low end torque I had been missing. And one reason I've never seen mentioned by anyone else is that I wanted a white car with stone interior and stone top - the GT comes only with a black top.
Do I miss having a V8 under the hood? Occasionally. But then I go for a drive along the ocean with the top down and it doesn't seem to matter anymore.
