What ford mustang should i buy the 2015 eco boost premium or the gt premium full equip?

Difference from both

If you can afford the gas GT… If you can't ecoboost, lol

I would go with the ecoboost I have one it was a great choice and just by getting it tuned will give it even more horsepower. I have a manual transmition but we took it to the drag strip and it ran a 13.9 in the mile without the tune and last weekend we took it to the drag strip again and we ran a 12.6 with the tune so it definitely makes a big difference with the tune.
