17 year old kid tried to buy my bracket racer :(

Doesn't sit easy with me, I replied to his email and explained to him that I do not think it's a good idea for him to have the car and told him that his parents will have to be present and sign some sort of disclaimer that I am not responsible for whatever he does with the car and that he will need to learn how to handle it.... I really feel it's way too much car for a hormone charged teenager... I further pointed out that it's not currently street legal...

I'm thinking I'm going to have to tell him no... I know there are some young guys here who are 17 that know properly how to handle cars like this, are responsible... but I don't know this kid and I always check emails on facebook/myspace/google to make sure they are not a bot before I reply to them... and it tells me he's 17.... =/ What say you guys?
