That is interesting...I have never seen a 1995 with the post update climate control. I had an 1996 S500 coupe that was halfway between the cars (effectively a series 2 but without side airbags or parking sensors) and that was an early 96 car.
Sold my 95 S500 Coupe a few years back, 73000 miles, FSH, 3 owners, for £2300. Awful car, every time I fixed something, something else would go wrong...and the rust!! Perhaps mine was an exception, but my advice is Unless you are wanting one badly, walk away.
