So I'm thinking of trading in my 03.5 G35 sedan and leasing a coupe. My car's trade in (KBB) is 17,800 but when I look on Infiniti's website at the lease calculator it's telling me my total trade and downpayment can't be more than $9,990.

Can't I just pay the full cost of the lease up front? If I can only put down 10K is the dealer going to write me a check for the difference? Am I going to have a problem finding a dealer who is willing to do this?

 

Yes, dealer will refund you the difference, ask them to write you a check on the spot, if not? its best to put it in writing just in case, and NO, you should have no problem finding an dealer willing to do it. As far as paying all the payment in one lump sum? that I do not know for sure, since there are interest involved, not sure if you have to pay whole interest amount or not , I am sure other ppl might tell you to put a lot of down payment is bad idea, cus they think if something happen to your leased car? the money you put down, will disappare!
