For me it wasn't just the power/displacement increase. I'm simple. I would of been happier than a pig in shit if I ever got my 3V to 450+ hp. These GT500's are just much more refined. The seats are more comfy, the interior is much nicer to look at, and the car handles and rides great. That is from the factory. I did gobs of work to my 3V to make it handle like this car does. It is just a much more refined car.
When I started my thread asking if it was a good idea to dump the 3V in favor of a GT500, I pretty much got the "duh" answer from you guys. One said its just the name, I beg to differ. Sure there are some 3V's and 5.0's that make killer power that will waste my 5Hundo, but I'm not out there racing every weekend. Sure, I'll make the occasional trip to the track just for fun, but that's not my MO for this car.
To each their own, we all have bad ass cars. So far I've driven my Shelby close to 1,500 miles in two weeks. I think that's more than what Darren puts on his car in 12 months... All I know is that it has been a blast!
