I dare not even look at my passenger side air vent.
I remember chatting to an (ex now) member who I had a few bit's off a couple of years ago.
He'd been on a forum, removed, glued and replaced the air vent.
Of course when somebody bought the engine and gearbox, they noticed it had probably the only 'unbroken' airvent in the West Midlands. They took an angle grinder to the dash board to remove it.
