They clearly want your late model leased Odyssey, so like Jay said, I'd offer them less ($350 p.m.) with no additional charges up front....or just buy it out yourself and sell it for more $$. They say the used car market has gone up a fair bit over the last year, so you should be able to make some coin by reselling it after the buyout. You're in the driver's seat.

Half of communication is listening. You can't listen with your mouth.
