I purchased a 91 210 Walk Around last Fall in the same condition. Boat was dirty, needed all new nav lights, gauges on helm were shot. No electronics.
Seller was asking $5500... offered him $3300 and he accepted.
Included 115, 1989 Yamaha that was running and dual axle trailer which was in rough shape but got the boat to me and to the launch ramp this spring. The boat was in the water and running when I bought her.
Cleaned up nicely, Very solid hull and she ran great when we put it in, but having starting issues now.
At the price I paid, I didn't mind putting some $$ and TLC into it. I also work at a marine supply company and get a great employee discount, so the parts and supplies don't hurt... too bad
