Epic mileage on that Beetle,it does deserve a second chance. Must have been loved by someone at some time & dispels the myth about hire cars ending up as being worthless.
I looked at the MOT history ( https://www.gov.uk/check-mot-status ) of one that a local Dealer had for sale but the previous advisories & failures for extensive rust repairs put me off it. Worthy of a follow up report in the future,good luck with it.
I agree about the interior. Gives me the boke just looking at the photies.
