id say he doesnt have a problem,just that you have big plans!
dont get me wrong its good to see man.if you dont set yourself goals you will never achieve them
having said that you are only young and (no offence)inexperienced on the roads.
if i were you id be looking at getting a run around car to gain crucial experience in before stepping into any high powered car.
this will also enable you to take your time with your project
good luck man
ps if your mum will match you $ for $ in a performance build shes the coolest mum ever!
