the little old lady who lives next door to me has a green Puch Sports 10 in her garage that she want’s to get rid of.
It’s in pretty decent nick although it hasn’t been ridden over the last two years
The frame looks like a large and it’s in green

is there much value for this in the retro market?

Couldn’t tell you what its worth, but just wanted to say it’s great to get bikes like that on the road again !

it’s a lovely looking bike, but i don’t have space for it otherwise i’d be keen to take it on and make it shiny again

Probably not a great deal, but if it doesn’t need much work, fix it and ride it yourself? If its in working condition than I wouldn’t expect more than £100-120 TBH. Unless the frame is made of something nice or it has interesting components in which case things get interesting!

even £100 would be fine, she was going to chuck it out but knew i was into bikes and asked what i thought of it
