???? Unless you made a very big down payment, I would think you are going to be very upside down when you go to trade in your van. Good luck with that.
From reading this forum, it seems like the dealerships cannot find a squeak to save their jobs. Read some of the posts about squeaking seats. Print one of them out and take it to your dealership for repair.
Or you could spray WD40 all over the seat joints to fix your problem.
