Iguess the real question is who works in the finance game??????

I've been here a few months now and have seen some guys that work for ford. I need someone w/ some knowledge of the finance game (SHUT THE FUCK UP PAT, OR YOUR PIC GOES BACK IN MY SIG ) Right now i have a deal on the table for an 04 gt w/26,000 miles, leather, power everything, only thing touched is exhaust otherwise bone stock. I'm trading my 03 gsxr 600 and 500$ only reason for the money is i owe 3800 on the bike still. total financed $18,800, dont want to end up like bedore any intelligent info would be appreciated. they're giving me 4600 for my bike
