No, I didn't buy this vehicle just to save gas. I actually wanted to have a little fun with it as well.The only regret I can think of is that the EcoBoost owners put in an order for their Mav when gas was $2/gallon cheaper and now want the Hybrid.

My 10 year old hybrid and the eco boost get roughly the same mpg on the hwy.
No regrets in that area at all.
Honestly, I'd have regretted getting the hybrid.
