I'm turning 16 and i wanna go buy a car, what age can i buy one? Do i need a co signer? i don't know but some one said you need insurance to buy a car so how do you do that? do my parents have to get involved? the car that i'm interested in buying is a 2001-2005 Lexus Gs 300 because they are cheaper now. Are they good Cars? I just need help in the process of buying a car
