I do not believe it sold.
If you had one as a kid and you wanted a bike to start a collection it was a steal! If you wanted to race it you would have had to put more than that into it to be competitive (just like back in 1977). A buddy of mine had one that had tons of mods to it; FMF pipe, Skunk Works carb kit, porting, milled head, aluminum swingarm, Fox Shox, fork kit. He was barely competitive with the RM's and YZ's.
Still this is a beautiful stock bike.
