Footman James came back to me with their quote. They couldn’t give me one because they don’t insure trikes!
Guessing the logbook says tricycle and not car, when I do a plate search on a Super 3 that’s already on the road, it does come up tricycle.
Maybe I should be looking at motorbike insurers. Although I don’t have a Bike license so I’d probably fall at the first hurdle.
