Gas isn't too bad of a concern for me. If I drive carefully, I can easily get high 20's for mpg. But if I do that, I may as well be driving a camry. So I usually get 18-22 mpg around town, which isn't any worse than I got with my older v6 camry since I had to have WOT to get passable acceleration.
When I'm driving really hard on back roads though, it does dip down to around 10 mpg. On the other hand, my smiles per gallon goes WAY up
