I just got home from picking up a mid 70's coffee Sprite at a good will for 7.50$!

I'd think that 50 to 75 would be a good initial offer for that bike in that market. While the Western Mass bike CL tends to be a bit relaxed, in Holyoke you're competing with a lot of college kids who might be in the market for something like that. It looks like its in really good condition though. The Brooks saddle, lamp bracket, gum walls, and sports style fork are all great details
