If you think your 1972 Ford F-100 with the mismatching-colored tailgate is hurting your sex appeal, you're absolutely wrong. While women might find a particular car sexy, that car's sexiness doesn't necessarily rub off on the driver. Top Gear Australia did find that some guys saw slight improvement, but I'd call their findings inconsequential: it has more to do with how attractive the guys is in the first place. Anything is an improvement if you dress for shit or never learned to brush your hair.
