My great aunt was married to the president of Dupont. They purchased their 16 year old son a high powered sports car when he turned 16, and he died in a crash shortly thereafter. Regardless of how responsible one is, the 16-20 journey is one in which a lot of changes occur. Owning a near race car may not be in your best interest.
The other concern I would have if you were my child is whether giving you this now actually reduces your pleasure in the long run. Going forward you will be lucky to get incremental performance gains even if you spend a lot more money. And a lot of the fun is the anticipation and having worked hard for something and then enjoying it.
In spite of the above concerns I suspect you will do just fine. Enjoy the car.
