Hi there, I imported my 67' 350 from the states in May 2017. I bought from a dealer in Naperville (
https://www.napervilleautohaus.com/), Illinois. I saw it on the web and got a friend of mine from Chicago to check it out, he said it was in pretty good condition but needed some work on it. I paid USD$26K for it and had it imported via Ship My Car. DON"T USE SHIP MY CAR . COM!!! They are a joke, use Golden Chariots or somebody like that (plenty of them are advertised in Classic American Magazine).
It was easy enough to get the Camaro into the UK, I paid 5% VAT (around £1K), but then I got Ship My Car to do all the MOT work (as they needed MOT's at that point), UK road legalisation and all that stuff. This was OK from them but they changed the clutch and messed up all the gearbox linkage so that had to be redone by a competent mechanic.
Most of the interior work I had to do was painting and restoring the seats, installing new kick panels (absolute bar steward of a job!), put new wind shield headers on her (another absolute bar steward of a job, she's a convertible) and replaced all the interior chrome etc. Even though some of the jobs were horrible, I still enjoyed it and still have all my fingers!
Now that I have gone through the pain she is working beautifully, I am just upgrading her to power steering and replacing the gauges and steering column.
I suppose my advice is, buy in the US and either get out there to view or get a friend to look over the car if you have any in the US. I was very lucky having a mate in Chicago who also knew stuff about cars! Also, be VERY careful about who you use to import the car, the importers I used whilst OK on shipping were useless at all the other bits. Also I bought the car in May and she didn't get to the UK until August, so have no clue on why it took that long. My guess is that they were waiting for another car to share the container with as I didn't pay for a single consignment (cost's a fortune).
If you have any other questions, feel free to drop me a line.
Cheers,
Paul
