Thanks ascaracing,
I've looked into the Motorsport Ireland Regs and I have to be 16 to do Rotax Max which is a bummer since I have to wait about 1.5 years. I haven't told my Step-dad about the idea yet. My idea was to either:
Buy a Max and practice and learn it until I'm 16 or
Buy a Junior Max / KF3 and race next year.
From the way you said it was £3500 for all that it seems pretty good for me too. Thanks for all the tips on where to get classifieds as I could bairly find any!
