Sounds interesting, but you might do better to buy a US Mustang and ship it over. I did a quick check at https://www.shipmycar.co.uk and it looks like importing one from Los Angeles, about as far as you can get from the UK and get a good one, would be 3634.85 pounds assuming the one you buy was valued at 5000 pounds. Of course, I don't know what your budget is so just pulled a number out of my backside to see what the rate would be. You can run your own numbers. They also take care of all the licensing work to make it legal there if you want, and I selected that as part of the deal for the 3634.85 pounds. Disclaimer, I've never used them, they were just the first hit on a search.

I don't know if you would want to keep it stock, but the running gear out of a 10 year old Aston Martin would be pretty slick in an old Mustang.
