Paying anything over the invoice price is insane. They can be bought for well under invoice. As soon as you drive off the lot that same new Jeep will be worth at least $5K less to the dealer (even if you have less than 500 miles on it). If they give you more, then they're making up the difference somewhere else. The used vehicle market right now is well below average and the days of paying over MSRP are well gone (unless the dealer finds an easy buyer).
