My '88 GT gets decent enough mileage, and once my '68's insured next week, I'll be driving it primarily on weekends during the summer, no different than I would if gas were cheaper. Gas prices aren't what keeps me from driving the '68, it's more about not treating it like a beater. That's what my Mazda pickup is for. For instance, I hit a deer last month with the Mazda, and while I felt bad, and it did tweak the bumper on the Mazda, no big deal. I didn't even bother to replace the bumper! If it had happened with my '68, after I spent over $2,000 and several months getting the Shelby nose and hood right, the price of gas would be the least of my worries.
