I think what he is saying is that he was looking for an R1, then found one for $3000 and it seems it legitimate, so he wants to buy that. The problem is that his parents won't let him buy anything until he's 18 and can buy it under his name.
And going back to the advice, I will agree with everyone here that the safest route is to get a smaller bike for even less than $3000, ride that for several miles (a lot) while you turn 18 (or 25 as someone suggested) and save for your dream bike. By then you will have a lot of experience and more sounding skills for your new all-too-powerful R1 when the time comes.
Also, if you haven't done so already, I strongly suggest taking the MSF's BRC course.
And don't forget to buy appropriate gear also.
