Are you being serious? I just asked what you guys paid and your bringing this crap into it that I already understand the consequences of. This is true and I'm just asking a question.
Future, I think you'll find that most adults don't simply answer the question at hand, they look at the entire situation. You'll learn that out in the working world after you graduate, this is what the world expects of you. As adults in most professional fields, we are trained to look at situations broadly.
I paid sticker for my car, so there's your answer.
However, the above fact is irrelevant. Why?
1) I bought mine two years ago, and things have changed.
2) I had an edge due to a lot of investigation
3) You've failed to mention financing, which may be part of the deal. If your dealership gets you to finance at a high rate, they can afford to sell you the car for less and make money on the financing.
4) You may live in a different state, and the supply/demand is different in certain areas of the country
5) I was able to order mine exactly the way I wanted rather than buying one on the lot...perhaps this has exactly what you want...not sure...but that's worth something to me.
So as you can see, you won't often get a simple one line answer from us because we are thinking about the broader situation.
Many of the people on this forum have kids and love their kids, and worry about other people's kids, and don't like to see strife in ANY family...so they voice their concerns.
Perhaps you can have your dad read this thread. If after reading all of this he still feels that he's doing the "right" thing, then at least he's making a more informed decision.
Are you the oldest child? In other words, has he let any other kids drive a very powerful car? Does he have a history with powerful cars...does he know how quickly they can "get away" from you? How is he legally/ethically buying it under the business...will it be used primarily for business use? Does he plan to send you to a high-performance driving school like Skip Barber or Bob Bondurant prior to driving this car?
I wish you good luck, but wanted to explain why IMO you're not getting short succinct responses.
And for the record, I don't have kids and I'm in my mid '40s. The first powerful car I owned was a '67 Mustang with a 289 2-barrel, which was like driving a VW Beetle compared to the GT500....be careful out there.
Good luck.
