Just drive a gt... Don't do what I did and bought a v6 and then wondered what the v8 would be like, and then proceed to modify the v6 to make it faster. I just eventually learned that for my needs and personality I needed a v8 so I traded the 14 v6 with 9k on the clock for a 11 gt with 5k on the clock. If you want something to just scoot around town in that looks good and is comfortable get the v6 they are definitely quick cars.
I totally understand when you say there is more than just the price tag to consider with the car as the v8 will almost always be more expensive in fuel and insurance, and if you get a base model you will most likely be disappointed. It was the small things like mycolor and ambient lightning that make me love my car all the more. Just test drive a gt, you will know right away which of the two engines suits you best. Then you will have peace of mind and never wonder, but what if. If you like the gt more you can find killer deals on used ones where people have already eaten the depreciation like I did I paid the same for my 14 base v6 that I did for a 2011 premium gt/cs with 5k miles on it. Either way you choose both are great engines Sent from AutoGuide.com Free App
