Acorn,
Without pictures it’s difficult to say with complete certainty BUT, my feeling is that’s a mighty good price for a generally good-condition new model SBH.
I should add however, that I like to bargain and if the bluing loss is more than commonly found, I’d offer less or say, “I’ll give you $450 cash out the door” and see if they take it.
My gut feeling is that may be a very decent deal -at least for my neck of the woods. If it’s in good shape, you should be able to get that amount back, no problem.
Let us know... post pictures, etc.
Regards
