look into KBB.COM. it will tell you how many will put down and how much you will have to pay it off and mostly its depends on your credit score. if you credit score like from 2.9 to 6.9 you will get a better deal and i will suggest you put like $5000 because about $1500 to $2500 will go into license and all paper works. so try saving your money until you get up $17k to $18 and you can get the car in cash so you can save yourself the headache from monthly payment and being upside down on your loan payment and by considering that you might be under $24 year of age your insurance will be high if you get the 2 door coupe because its sporty car. so consider lesson before you buy it. good luck.
