Imported my Datsun SSS 51O from South Africa to the UK. It’s not complicated to UK register the car but you will pay import duty/tax on bringing it in that isn’t cheap. I guess you know that already. Hope it works out for you. Is it coming into London Gateway ?. FYI it will arrive with NO fluids whatsoever so don’t drive it until all the fluids are in the car. Best to get it flat bed delivered.
