I came across this website where people post up pics of vehicles they spot along with their reg numbers. Out of interest/boredom I searched for my own reg and found I had been spotted twice, once at a show in 2015 and last year on the Hamburg trip. So I delved deeper and searched on all Deloreans spotted in the UK. There are quite a few!
Theres a few from the Hamburg trip there, Justin, Mec, Myself, Gareth. I also spot Mike Ward at Brooklands, Darren C at Goodwood. And a few plates I don't recognise.
