The engine and year sounds right. The tranny should have a serial number on it too and you cab call ri and verify the year as well unless someone swapped trannys at some point they should be able to verify the year of that too. As for the price issue, that's really up to you. The asking price does not seem out of line to me and a few hundred off would seem like a pretty good deal. Could you find a better deal, sure, but there seems to always be a better deal out there somewhere.
l like to buy stuff and no I don't do payments!
