A few years back I was at a gun show and the guy in front of me had a Remington M600 carbine in 6.5RM. Dealer at a table asked if he could see it.
Dealer-How much are you asking for it?

Seller-I would like to get $800

Dealer gets a shocked look on his face and responds
But they only sold for $149 when they were brand new

Seller-Give me my rifle back

Dealer acted insulted as the guy walked away
