Short answer: no
"I've seen them sell for $3000" he's full of shit... You can check eBay's completed listings right now and see they fetch +/-$1600 TOPS, in better original condition with the same or less miles.... Maybe there was once a cl90 that sold to someone for that match but not likely and definitely not in that shape... Yeah it has low miles but that is definitely NOT original paint or seat obviously. And from what I know, all 90cc Hondas had silver tanks. Not other colors. I could be wrong there... Personally I would think he could get 800-1000 for it pretty easily in the spring. It just snowed here the other day so local bike sales have took a huge decline in number of bikes on the market and current "market" values.
