I have a chance to buy a blue 70. It doesn`t run but the compression sounded ok. pretty good plastics, seats rough, tank has a dent but no visible rust inside. Whats the going price on somthing like that. I think its gonna be make me a offer kinda deal and I need to have an idea whats realistic. No its not gonna be $20 bucks but I was thinking no more then a $100 is that fair or to high for that even being the rare christmas one or isn`t it. Thanks
