Actually, I thought CORTDD had some good advice. I didn't read it as putting down the OP. I wouldn't go to 72 months on a car loan either but to each his own. The OP can certainly do as he chooses and I don't know all of his circumstances, but he might want to shop around for a better finance deal. I would hate to see someone get screwed by the bank (even though it happens all the time).
I've been assimilated. 6MT/ZPP/18"/PS extended.
