As Egocentrist pointed out in the comments, lots of Marines drive Mustangs, so in an effort to be different, he suggested considering Sex on Wheels, otherwise known as the Pontiac GTO. I can get behind that, and out of the ones I see on E-Bay, this one looks like a reasonable alternative to the Chevy Volt.
The current bid is $17,099 and it has less than two days to go, although I noticed that the reserve is not met. You’re not going to get a GTO for what you can pay for a Mustang, there aren’t as many of them. But there’s lots of late ’60s, early ’70s muscle cars out there and something should catch your interest at a price that would make buying a Volt look criminal.
