I still don't understand why people say the v6 is such an underpowered car. What other car out there will you buy BRAND NEW that gives you the power a v6 mustang does for about $13,000 (one without any options)? I bought mine at 17 and think it was and is a great first car. No doubt the v8 is better, there's nothing like driving a 2004 cobra (driven my bro's a few times, car is like a bat outta hell).
Personally, I think that for the amount of $ you pay for a brand new v6, it's a bang for the buck car.
As far as the GT resale goes, it ain't all that good. I remember before my brother bought his 04 cobra, he had a 2002 GT that he bought in august 2002 for $23,000. Sold the car a month and a half ago for the cobra and barely got $14,000 for it. The car didn't even have 10,000 miles. Looking for resale value, then get a snake or a corvette.
Gas consumption...I gotta give it to you all. The gas mileage on the v6 is pathetic. It's about the same as the GT.
