Seat Ventilation (more)
I have used the (3 speed) seat ventilation feature in my SL500 regullarly for over 15 months--It works very well, and provides significant personal comfort improvement, particularly on long trips.
As I understand its operation--air in the cabin is pulled through the little holes in the leather back of the seat--so whatever "conditioned air " is in the cabin passes along the clothing on your back, hence eliminates a moisure (SWEAT) built up. By providing that low velocity, almost undetectable air movememt, moisture build up is prevented, and your back feels very comfortable. The air velocity is so low, and no fan noise nor air noise is present in this system.
I do find that I feel more comfortable by NOT wearing heavy clothing or coats, because that insulates/isolates the body from the back of the seat--and perspiration might still occur "inside the outer ware". (like raining inside of a rain coat that doesn't "breathe", but not getting wet from the rain)
Based on my experience over many months, I highly recommend the Seat Ventilation feature on the 2003 SL 500.

seat ventilation (more again!)
The seat ventilation IS NOT SUPPOSED TO COOL - it is supposed to ventilate--remove excess moisture between your back and the seat back--so it feels comfortable. Mine works fine--as intended!

The seats have a number of small fans made by the German manufacturer Papst whose products are more often found in professional electronic equipment.
I agree you cannot feel a blast of air from the seat ventilation but giff is correct that it improves driving comfort by keeping you dry. As for whether they are worth the money, only you can decide the benefit in comparison with the other options you may be considering.
The blue LEDs are pretty cool anyway...

Also in addition to the leds, (ultra cool btw), they start out like this
The bottom half of the circle is a button, so is the top half and the led's being the splitter.
You press the bottom half once, and all three blue (cool) LED's light up, one more time and only two, press it thrice and only one LED is lit up.
The top buttom is for heating, I can't remember the sequence for that, remember i'm in Texas. It's hot all year 'round.

In the US spec cars, the cooling is indicated by blue lights and the heating by red. It looks like your car is equipped with the option for both, but I am not 100% sure as I think the cooling in mine had a fan icon like the BlueSL post picture above. You know whay I am not sure? because to me the option is useless. It is not an AC seat. It merely blows some air out the holes to provide comfort. It can help cool a hot leather seat in the summer (sort of) but it's not going to cool you after a work out. If you cannot hear a fan blowing when you use the bottom option then it is eather not working or a missing option in your European spec car. Try to use the featuer when sitting at idle withthe radio off. you should be able to hear the fan in the seat back if it is working.

Looking at your buttons, I'd say you do not have the ventilated seat option since you do not have the correct graphics on the controls.
As for why you have perforated leather, it was probably more cost-efficient to equip vehicles with certain options with less types of leather and just not build the seat with ventilation fans. If you have seen other SL55s with non-perforated seats, they probably had other interior trim features which led to it.
