If you mean can you import a LHD into a RHD country, then it depends on the country and local laws.

In My country Australia, there are strict laws. Mostly covering LHD vehicles of 30 years old or more.

There were actually two W124 5.6L 32V builds done as RHD in the UK.
If I recall the builds were done by Strattons.
Only one has survived !
