Hello. I’m in Enfield ( north London) and cheshunt ( Herts) can let you know when they arrive, your more than welcome to have a drive of it.
Re shipping with all the paperwork, clearance, insurance, some inland transportation and ocean freight, it works out about £1400 from the east coast. Always try to purchase the car as close to the ocean as possible. This saves you on transport costs. ie not from Kansas. West coast shipping is more expensive and takes longer as the ship has to go through the Panama Canal. As for import tax/duty whatever you wish to call it, it’s pretty straightforward. For vehicles 30+ years old ( so 1981 is OK now, as you can say original registration date was 02/01/81 ) it’s vehicle invoice price + shipping price giving you the total landed price. The Dollar price paid will be converted to £ pounds using HMRC’s monthly set rate. That converted £ price will have VAT at 5% added giving you the total cost to you. Anything after 1981 it’s landed price + 10% Duty + 20% VAT.
Hope the above is helpful.
