I purchased this car because I always wanted a Mustang. And the dealer was offering some pretty impressive rebates at the time. I love the way it looks, but not the way it performs and sounds. It is still definitely a quick enough car to get a ticket or land yourself in jail. But compared to other V6 equipped cars (Altima, Accord, Camry, Malibu) the engine simply sounds rough and unrefined. It is also much less powerful. I didn't know this when purchasing the car, but the V6 is basically a hand me down from the Ford Explorer.
I also test drove a GT Premium, and honestly loved it, but $4 per gallon fuel prices at the time weighed heavy on my decision to buy a V6. The handling on the GT seemed a little firm but much more composed. But I'm not expecting a Mustang to ride like a Lincoln Town Car like some people seem to.
Fuel mileage is not that great for a V6 in my opinion, mine has ranged from 17 to 26 MPG, maybe over 27 on a real good day. With the V8 being only a few ticks lower, I feel like I've gotten the short end of the stick. Outside of fuel mileage, everything the V6 does the GT does better.
The front seats are comfy, and rear, well it's the same old Mustang. If you're over 5 feet tall or older than 12, you won't be very happy riding in the back seat.
It's still a sweet looking car, but I may look for a new GT V8 in a couple of years. One thing's for sure, I will never take dealer stock again.
I also have the option of buying a friend's 1989 GT 5 speed. Him and his wife are having a baby, and they need (or think they need) to clean out the garage to make room for a minivan, wagon, or SUV. I've borrowed the car occasionally. It's an old rough-rider, but at over 170,000 it still runs like a swiss watch. And the fuel mileage is nearly as good as my V6.
