You mention the tune like you think it might have hurt you a little but I'm not sure that's necessarily true. Might be, but then again, might not!

As for what I was trying to say, if you were driving an Ecoboost, it's likely you'd be well into the low 30's, mpg wise. I'm still in the dreaming stage. I've got other financial obligations that I need to get out of the way before I can buy another car and I want the convertible which adds a bit to the cost but if I can swing the GT, I will opt for one but for me, it'll depend on a number of other factors. I'd be happy with the turbo and even the V6 if they'd offer it in premium trim but I do understand the allure of the 5.0.

Drive Safe,

I know the 5.0 will run on either in stock form with the understanding that you take a performance hit running regular. Do your mods require premium all the time?

Thanks for any info!

Now that's a combination. The Mustang isn't even in the same league as the Corvette. Both are great cars. If you can afford the Vette, go for it but I'd have to go Mustang. The Vette is above my pay scale.
