They retail at £300-400 new but looking on
ebay, with them being sold by
Evans, there's a lot of them around. Plus being ridden generally by adolescents they take some hammer and get scant maintenance, so the prices 2nd hand are sub-£100 for average examples.
I know *a bit* about them having bought one for a relation; tbf they seem to be good bikes - really light, well made, serviceable etc. but they're not collectable... if you had an original, pristine raleigh burner, different kettle of fish, but who knows in 20 years time when said adolescents want to relive their youth...
