I love the 2005-2009 GT body style. It's what got me back into Ford. I like the front of the 2011-2014 GTs, but that back end just kills me.
V6- Pros- cheaper insurance, gas mileage, fewer miles, still very reliable.
GT- Pros- torque, looks, sound, tons of performance parts, already done most of it's value depreciation
V6- Cons- fastest I've ever seen was like an 11.8 1/4 and it had over $10k in it, still a new car (won't be worth as much in 10 years)
GT- Cons- gas mileage, higher miles (I had 120k on my last GT, kicking strong), insurance
I personally prefer the 2005-2009 GTs. If the 2008 GT has brown coil boots and the 2008-2010 style heads, I'd jump on it. If insurance and fuel economy are an issue, the 3.7 V6s are great cars.
