Can you buy a car at the age of 16?

In most US states, you cannot buy a car at the age of 16. While you might be able to enter into a contract, the legality of that contract is questionable, and most dealerships won't sell to someone that young. You'll need a driver's license, and usually a provisional license isn't sufficient for purchasing a vehicle. The specific laws vary by state, but generally, you'll need to be at least 18 to legally enter into a contract to purchase a car without a parent or guardian co-signing.
