How rare is this and what's it worth?

It used to be that way with the Ford Model T, Model A and Deuce guys....if they thought you were going to "hot rod" their "stockers"...they wouldn't sell the car to you.

My dad would say "sure I will keep it stock"...2 days later it would be stripped, lowered, chopped, sectioned (whatever his mood of the day) and sportin a small block Chevy.
