first off that is a bum deal and I feel for you!

But alot of people buy used so don't feel like a heel. Nothing wrong with it as I purchased mine used too.

I would definitely have a dealer take a look at it just to make sure there isn't anything you are overlooking and/or if that really is the problem. I wouldn't necessarily take their word as gospel but would be good second opinion.

Lastly, there is alot of wisdom on these boards so take the steps already mentioned and use it to your advantage. Good luck!
