How much would you guys pay for a running Honda CB77 Skyhawk in average condition?

I'm tying to get one but idk how far I could take the guy down. He's at 15k and I think I could get him lower if I had a reference. There isn't a lot online. via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/apoa5k/how_much_would_you_guys_pay_for_a_running_honda/?utm_source=ifttt
