I was tempted to book it in for an MoT locally and drive her back on the US plates, but finding out problems is not ideal on the A12 .......so will get it collected!
I will drive it back for you if you like, never drove left hand drive but @S1mon has so he will come with me for support, we can drive it about for you for a few days to get it run in then leave it at that mot station up the road for you when we are done. All you have to provide for this service is some petrol money, a lift up there, and then just some money for food, oh and a bit of general spending money if we stop somewhere nice. I think theres an app you can get to track our progress now. Let us know by two or I'm not doing it, I'm busy
Oh nearly forgot you have to get these (in a U.K. colour combo) to be cool http://www.platemyride.com/plate-simulators/usa-classic-plates/
