The Brompton market is completely nuts at the moment, which considering how many people are now working from home and not commuting is strange.
I’ve been following the used market with saved searches on Gumtree and
eBay as I’m looking for another one for Mrs Gunk, anything sensibly prices goes in minutes and then reappears a couple weeks later with another seller for up to 25% more. There are a couple of very active trade buyers in the south east with quick fingers, I’ve found it impossible to buy anything, when the supply comes back to normal, I’ll probably just buy a brand new one instead.
