If you’re in London then go and see if for yourself. Take a chain checker and see what the chain wear is, that’ll help prove or not the 250 miles claim (which is pretty unlikely, tbh), check the rim wear, if the tyres are matching (if not, at least one has been changed which won’t have happened in 250 miles unless it was due to bad luck), the state of the bar tape, stuff like that. Or maybe take someone along with you?
Regarding the shifter, that looks like it’s been down the road on the r/h side. It looks like matching damage on the rear mech body. Looks dramatic but it’s probably just a slide.
