I'd like to do that eventually...I think you start as just drying cars as they come out of the wash, and move up from there. Especially when rich people bring in their CTS-Vs, Lotus's, Vipers, etc.
But drying cars isn't all that bad...the girl who told me I should apply said on good days she makes $30 an hour with tips.
There's a house a few miles away from my house that has a Lotus Elise. And someone in my neighborhood got a Lamborghini Gallardo this summer, but I haven't seen it out at all since winter started. And my friend's dad just bought a new CTS-V.
