whats the minimum amount of money you'll need to put down?

That's depend how long you wanted make payments...low or not down payment long terms lease or good down payment can payoff your loan sooner...common sense

All I put down was my 18 years old trade

Honestly it depends on you and/or your credit and income(the bank may ask for a specific amount of money down and etc. (Ex. I bought a Lexus for $24k after taxes, financing and fees $31k in which I put $0 down). If you can, try to put down for the taxes and fees.

Ok cool....was there an option to split that in two payments if needed to be?

In my case 1k
