as always it depends on market. around here you wont see a decent (which a centurion lemans is.) bike even in bad shape for 60 bucks. anything that you can ride at all is usually at 150.. as long as its not from target. Id probably give him 60 bucks for that bike and be pretty pleased if I could get it back on the road after another 60 or 70...
I am a bit biased as i quite like centurions.. I just picked up an ironman for $120 that needs work for sure.. but they are a worthy bike to spend some time and money on.
