Well I have 2 more months of high school and I finally graduate!

I plan on making a deal with my parents that if my grades stay up and I get a job and hold it that they will help me buy a new Camaro Convertible.
I have worked 2 jobs, one at Wal-Mart as a cashier and then secondly as a pizza delivery driver, neither one of those fit me at all. My family friends say they just don't see me as a clocking in and out kind of guy and think i should go into sales of some kind, but I was going to ask some suggestions from you guys and see what you think some decent jobs are for someone my age.
Thanks in advance guys.
Future owner of IOM 2LT Convertible, IO Interior.
