Hi there!
I'd say for a VW Golf it's not worth bringing it over here - best bet would be to sell it off in the US and then find a similar car once yer over here. I've imported a 2003 Ford F150 Harley Davidson (which is now for sale after enjoying it for the last 16 months) and generally speaking its the more 'interesting' US cars that get imported here. A good friend of mine is a vehicle imprter, I can pass you details of how to get a hold of him if you message me if you'd like - he knows the in's and out's better than I, all the SVA testing, VAT, import duty, shipping and insurance handling etc etc. Becuase my and my bro's F150 is less than 3 years old, we don't need an MOT nor have we converted the lights as yet, hopefully it'll sell quite soon and so the new owner can look after all that stuff.
I can't remember the exact figures for our shipping but it was more than $400 worth that you mention, for that price it'll probably be 'open' shipped, this is more risky as the car is not enclosed in it's own container and sealed (which is the best way and more expensive of course!) we were lucky, the F150 arrived very filthy and dirty on the outside but no scrapes or bangs, nicks or dents which apparently is 'very' common with non enclosed container shipping. From memory we paid something like $1200 US for the shipping with the enlosed recommended way being a fair wedge more (i may be wrong now as pricing may have changed)
the SVA test was £250 or therabouts- not sure if the fee varies for different cars/trucks/vehicles etc.
LHD is very common in the UK, the truck was particularly easy becuase you sit high up and can see 'over' other cars to 'see' the road ahead for overtaking. Sports cars which are the main type of LHD car's you'll see here suffer from that vision , but apparently once your used to it it gets easier.
The downside is that any drive throughs, car parks , ticket barriers are on the right and you'll be sitting on the left meaning you have to lean over. A particularly excellent item i used was one of those 'grabbers' you sometimes see disabled/street cleaners carrying! just drop the electric window, pick up the grabber and reach across with it and pull the ticket at the barrier you're at!
Hope some of this helps!
