Vented Seats
I have been following this thread.

If he has any success I will be doing this mod in the near future... Before the Vegas Summer.
But it still wont be as good as Lexus.
I test drove a Jag XJ and it seems that Jag has the same crap because they dont work in the Jag either.

Infiniti's actually air conditioned seats, they have a separate cooling element that blow a refreshing breeze on buns, upper legs and the lower back / lumbar area. Why MB only offered vented seats and it is not even an option on E350 is beyond me
But MB Driving Dynamics truly like no other car...

Sorry, just picked a random representative post. Not aimed directly at your post.
What's this about feel? Why do you have to feel it for it to be effective?
Here's how you tell it's effective: Take a nice long drive (6+ hours) without a vented seat. Get out of your seat, have your back and butt sopping wet from sweat. That's ineffective. Use the MB seats and take the same drive. Always, every time, no back or butt sweat. No, I don't always feel it (unless I turn it on after sweating awhile), but it's damn effective.
Now, if you want your butt frozen, you're probably better off with a different car.
I had them on an E430 and couldn't have been more pleased with how I didn't sweat on a long drive.

There is ABSOLUTELY no difference thus there are ineffective.
Also I judge them by experience in cars seats that actually have cooled seats.
And MB seats are nowhere near to other competitors.

Now, if someone pointed to a specific problem with ventilated seats vs. cooled seats, aside from "feel," then maybe there would be an issue. What exactly do you want? Do you want your backside to feel cold? Well, then you need cooled seats, not ventilated ones. If you just want your backside to be approximately the in-car ambient temperature (which is "cooled" by the air conditioning), then MB has it just right, in my opinion. I don't want my front side at 70 degrees and my backside at, say, 50 degrees. As I mentioned, I do not notice the cooling if I turn on my seats early before I start sweating, which sounds about right to me.
One way to see that the cooling is effective is to turn it on in the winter. I've done this by mistake, meaning to turn on the warmers. Before the interior ambient has had a chance to warm up, the cooling feature is absolutely bone-chilling. And the difference between off and on is obvious.
I am struggling with an analogy here. But given the choice between two AC systems, one of which I could tell when the AC is on and the other of which I could not tell, I would choose the latter unless I could identify specific issues that related to my discomfort.
I'm addition lots of people buy heated seats in warm climates for back pain helping to relax tight muscles, many also get tremendous relief from cold as it helps with inflammation.

When I drive in a friends Lexus RX, if you turn the seat to the highest setting its is cold, very cold but you have the option to turn it down which I do. The highest setting is really just to cool the seats at a faster rate... much like the highest seat heat setting in our cars heats the seats.
My main point is that in the summer the seats will get hot, and they will cool at a much slower rate than the cabin air, especially if you plant your hot rea end and back on them. Ventilated seat do nothing to cool the seats.
The only time they work is when the seats are not hot... but then what is the point if the seat is not hot?

The seat coolers are indeed very effective, not at cooling the seats, but at keeping your backside sweat-free over longer drives. And they are non-intrusive in the sense that you do not notice them working, which is also nice.
You want something different, a new option. That does not make the current seat coolers ineffective.
The question I asked at the beginning of my thread was how effective in actual cooling on the "cold setting", not venting.
With respect to venting, Porsche's design is quite effective as they draw air through the seat and pump the warm body air out the back rather than trying push it through. Here's some comments from current owners which are all very positive unlike the majority here. I did not have these in my 997S but plan on trying them this weekend.

In any case, I'm perfectly happy with the seats as they are. I just finished a 1.5 hour drive, and my backside was completely dry. But I fully support your position that others prefer something different and that MB should offer that something different as (at least) an option in a car of the caliber of ours.
We all have irritations with our cars. Mine is that the hot setting turns to low after a while. Why the **** can't I keep it on high with resetting it?
I was told by a neighbor today that Jag's have airconditioned seats and they are standard equipment.
