Reader Question: What Car Is This?

CC reader Martin M. sent me this picture and this question:

Not much to go on but I’ve spent hours trying to identify what car this is in the attached photo.
It appears to be left hand drive, four door, but the louvers in the rear and what look like lift-type door handles have me perplexed.

Soft top? Frameless windows?

It’s driving my friend and I mad!
