I started out with little or no experience as well when I was 17. Most shops don't mind. As I was told it's "less to break down". That's why Marines are so young, right? Anyway, most shops are glad to have a part timer to take out the trash, grab coffee and assemble comfort bikes. It's fun and you really get a good feel for the business. I met a lot of cool people this way...unfortunately I had to quit in search of more money, but since then I've worked at several other shops and worked myself up the ranks to a mechanic. Have you applied anywhere?
