A couple of years ago, my bike was stolen. A lovely relative offered to sell me their ancient bike for a runaround as they weren't using it and it was just gathering dust. I gave them £60 for it.
I've recently bought a new bike. I put the old one on gumtree for £35 thinking I might get £30/25 for it. Phone lit up like a Christmas tree - turns out this particular model is a retro collectors item. I've now had a look online and similar condition models are going for £200-300!
My problem is, although the bike is mine and I paid relative for it, a part of me feels I should split whatever it sells for with her. She obviously had no idea of the resale value or desirability when she sold it to me, and she must have paid a fair amount when it was new as it was state of the art back then. But then if I hadn't bought it she probably would've given it to a charity shop or taken it to the tip, so she'd never know its value anyway.
WWYD? Keep the money or split it?
