I'm still watching prices all over the country and its creeping up because of summer weather. The high end and lower end of pricing is not correct in any of the books.
I think some sellers see a high priced viper listed and base there asking price, up or down depending on the other guys add. Not bonified selling, cash in hand, keys in the ignition transactions.
When I get serious around August, I will make honest cash offers and I'm guessing I will get a lot of negative responses from guys that have bone stock good condition vipers priced in the low 50s when they should be priced in the low 40s, and they should be ready to take a real 39K offer if they actually want to sell.
