Yeah I did suspect the can of worms thing. You could well be right with it hanging around for a while in a shop actually as I used to work for Vauxhall 20+ years ago and some large dealers brought a 20-30 cars at a time to get a big discount and registered them as and when they sold them, should have thought of that myself but the worry monster was befuddling my brain 😀. Cheers.👍
