Interesting. This may be something like the fact that I owned a 540i for 3 years and sold it. I bought a E430 and liked the lights staying on when I shut the car down. I bought another 540 and found that the lights will stay on if I set them. SOOOO, for 3 years I had the other car I didn't know they existed.

I can't imagine a 124 car doing this though as there is no auto-up position. There is a auto down position so I could see them doing an auto down. And after my BMW experience I suppose I could have missed such a key operated window operation as I would have no time for it as a function anyway (I presume the function is to allow all the hot air out of a parked car - I ain't got time for that).

I'll try our shop 1991 wagon on Monday, now that you got me all excited.
