Most people don't think about it. If you A)Love cars and B)Love people you will love this job. It's the easiest, most basic, funnest, least stressful job I've ever worked. Just work at a nice hotel to drive the nice stuff. Plus you can make, with tips, over $20 an hour! I get tipped for retrieving cars like this:
Audi R8 V10 Spyder (today actually, I'm still ecstatic) and all other models
Porsche all models
Aston Martin V8 Vantage
Many AMG model Mercedes
Jeep Grand Cherokee SRT8
and on, and on, on
Kids, for even a summer job, it doesn't get much better. And your interpersonal skills get so amazing and you learn to have unlimited confidence.
