You sure your car has factory air, not an aftermarket system?

It all LOOKS to be original.....

Doubt many if any 'after-market' kits/fittings took place at my car's age (1980) here in the U.K. where in those days, air-con was considered a real luxuary, and rather expensive option.

I have leather seats, (Black) and the 'ribs' as far as I can think go all the way to top/bottom of the seats--Smells like leather and doesn't have that 'MB Tex' look....

BTW, Which 'russian-thing' are you checking on....?--

Is it This one-

And its VERY possible that the seats were CHANGED-OUT at some point maybe to replace the original's that were worn or damaged. So what had TEX now has Leather or vise versa, its an easy swap.
