Need Help pricing my Old 4 wheelers

This is my first post here but I would like to get some advise. I have a 1989 Honda 300 fourtrax. It needs a carb or carb rebuild, coil and a battery. It has new tires but is not currently running. I also have a 1987 Honda 250 fourtrax that is running( can pull start) just needs a battery. We just recently replaced the carb. I would like to sale these to purchase a newer one. Can anyway guide me in the right direction with pricing to help get these sold. Also would you recommend getting the 300 running before I try to sale.

Thank y’all for your help!

I should have pictures in the next couple of days of the 4 wheelers if that will help.
