Sounds a bit high. I was just quoted $13750 for a B7610, which is normally about $1000 more. This price is before tax and includes delivery. It includes folding ROPS and industrial tires, which I think normally add about $250 to the price. Also this includes the bigger LA352FL-1 FEL, which adds about $250 over the price of the LA302FL-1 FEL. I'll also add that I live in an area where deals are hard to come by, and I'm about 65 miles away from the dealer.
Check the following site for an idea on how much you should pay, but keep in mind regional differences might prevent you from getting as good of a deal:
If that price includes sales tax I would say it is pretty good. Regional pricing varies and you don't have your profile filled out, but the B7510 pricing I have in my files is a bit lower than your quote, but factoring in sales tax and steel price increases, your quote is right in line with some of the pricing. It is not the best I've seen but it is not the worst.
