I once bought a second hand Toyota Celica, a Japanese import. It's engine had been almost wrecked, I found a local company, which imported emissions failed engines from Japan, to resell, bought one, and had them drop it in, because I was too busy. 'Drop it in', they did - I spent several weekends, redoing properly, much of the work, they should have done!
The Japanese, drive on the left, just like the UK, but their emissions standards were much tighter than ours. That car proved to be a great little car, but eventually, kids forced me to find something with more space.
