Old Car Tax and MOT Status

[TonyF1]

Sold a Mini Cooper S to Arnold Clark March March 2021 for an OK price as expecting MOT fail as the last one had an advisory list as long as your arm with extensive corrosion of the sills being the least of the issues. It was my wife’s car and we’d bought a new A5 for her.

Looked on gov.uk in April 2021 and like magic had a new MOT with zero advisories. To say I’m surprised is an understatement given the corrosion on the sills was visually obvious and some of the other advisories had been on previous MOT’s.

Thought I’d have a look last week and MOT and Tax now expired over a month ago. AskMid says it’s insured so scratching head on why you’d bother to insure and not tax/sorn. Any obvious scenarios?

Person who bought it from AC selling already and its now sat on another forecourt and the owner hasnt cancelled their insurance for some reason.
