Hi,
Overall, as per above, it won't really be worthwhile to bring a 'bread and butter' type car in from the USA here. The shipping costs, import duty and any VAT, modifications needed for the vehicle to be made UK road legal will easily be £3-4000 I'd have thought.
Importing cars from the USA only really makes sense when it's something much more interesting and/or rare

I miss the F150 I imported and had for around 8 years or so! I've got my eye out on what vehicles I want to bring over next time I'm able to

Contrary to popular belief, left hand drive and/or larger vehicles can be run and used here on UK roads relatively easily, although it does take a little getting used to

Insurance isn't as hard to arrange as you'd think, and can be very nicely priced, selling on also can be easier as you have the Euro countries to export it to (or a new buyer to arrange their own importation) and they're all left hand drive cars countries. Perhaps one of the biggest misconceptions is 'fuel economy' - many people forget that the US figures for MPG are USA sized gallons and the UK has a larger equivalent. Direct MPG economy when you take that into account makes USA vehicles really very good for exact same models between the two markets.
