just wondering if your under 15 but older then 12 can you buy a new car?

(1) Unless you can pay cash, No. The law prohibits anyone under 18 from entering into any sort of contract, including a sales contract to purchase or lease a new vehicle.

(2) It is unlikely anyone is going to give you direct control of that much money.

(3) One of the main causes of unhappiness in the world is false or unrealistic expectations. You're off the chart in the wishful thinking category.

I'm not sure whether or not you would be allowed to buy a car, but I can tell you it would probably not be a good idea. By the time you can drive, that car would be a few years old, and from what I can tell it seems like you would want one of the latest vehicles. The car you think is cool now might not be so cool in a few years.

Its doubtful you'd have use of that money until you were of age.

For that exact reason. It will most probably be put in an interest bearing trust until you are either eighteen or twenty -one.

You can buy a car if you have a driver's license and proof of insurance

Oh but for summer and bored children of America. Why even bother to answer?
