MZ/MuZ Riders

I hate it when my bike gets into my am radio, lol. My neighbor is a junk man and he had an old artic cat 4 wheeler in his pile. I got the spark plug cap off it and put it on the MZ and rode it for 30 min with no problems. The only problem is I have too many motorcycles and I decided the mz wont replace my gs bmw ( like it would ) and I am thinking strongly about selling it. Since there are so few imported, less the 15 is the best I could find out, does it make it more valuable or less? What price should I ask? I'm thinking $2500 would be my lowest I would take from a stranger but would rather sell it to a member here. Any input would be great before I list it for sale on this site and Craigslist.
