I worked at Domino's and drove a 1990 RX-7 stage two HKS back in 1993. I always got comments when I drove up to peoples houses. I made about $13-15 per hour which wasnt bad being in college. I use to get the same comments about my parents but it is possible to have a nice car and still work a lower type service job.

In fact I have a few employees that drive Range Rovers and Audi and they valet park. Do there parents take care of them? When I worked for another valet company I use to have a e34 M5 and I sold that and got my first NSX.

It is not how much you make but more about how much you keep. It is most certainly possible.
