I figured that even if I got a car that got 33 mpg, even after 5 years, I'd still be 3000+ lighter in the wallet, and that's comparing driving the truck to the MINI everyday, which I won't. I will most likely drive the Vette 80% of the time, and I'll be ****ed if I'm going to let it collect dust in the garage. The car was built to run, and I will do so. When it racks up a ton of miles and starts crapping out (and thats IF this ever happens), I'll buy another one, or maybe the charm of owning a Vette will be gone, and I'll buy something that gets great gas mileage. Thats a long way off, I'll just enjoy the Vette now, and worry about the mileage in 6 or so years, when it approaches 200,000 miles. Maybe if I keep it until 500,000 Chevy will give me a new one.
I love the truck, so I'm going to keep it. It has been very reliable, and it is one of the few vehicles that I've owned where I wasn't looking to go with something different after a year. The only truck I think I'd go for instead is a G500, which is entirely out of my price range, and I wouldn't spend that type of $ on a vehicle even if I had it like that, which I don't.
18/22 mpg isn't the end of the world, considering I really only drive it a couple times a month. Chances are I'll end up working closer to home in the future, and this won't be such a big deal.
Thanks for all the replies (well, some of them), but lets let this horse die.......
