Darn I missed this one and was only a few hours away.... bummer.
They still have them but I don't think they are supposed to advertise a price like that. They have quite a few and they need to move them. I walked in this week and bought a 2018 800 Pro 155 for $9000 plus $299 doc & assembly fees and sales tax. Had to finance through Idaho Central Credit Union, no early payoff penalty but they asked me to pay six payments which I will do. I immediately paid most of it off just to keep the interest nominal. They must get some sort of kickback from the bank - I don't mind writing a few checks if a bank is paying some towards my new sled.
I do think its important to support your local/favorite dealer. They aren't my favorite, but they are 1/2 mile from my house so they know me and give me great deals on parts/accessories and their service is so far OK. I do most service work myself anyway.
