Welcome to the forum, I also was on here long before I got my 126. I'm from Belgium and as far as I know you can drive a LHD car in UK if you make sure your headlights are right for UK. Long time ago I heard about stickers that you needed to put on the headlights so your lightbeam would'nt blind RHD drivers. Don't know if those are still used, or ever were for that matter. Anyway, you should not drive a car anywhere that will blind the oncoming traffic.
