I found a 1980 i believe Gadabout 2 trike with title- it needs a front brake cable and front tire-supposedly thats it. It shows 3100 miles- told runs great- just has light rust and very light red paint fade so a good detailing is needed. What kind of money should i offer if its seems tight -actually want for my mother as a surprise to help her get around easier. Also any clue on weight capacity? Thanks ohh it has spokes in the back and a mag up front guessing thats how they came.
