OK. There is a problem for ya. Because of your age, you technically can't race the CP class, so I would recommend J/P, I think GP/K or something similar until you gain some seat time. Once you have two years experience, You can move to A/P, but still no Oppy's there.
My suggestion to you would then be to build the best chassis you can, even purchase a used one so you can see what works for you and what doesn't, start in the aforementioned classes, and save your money.
