Adding Ventilated Seats Option
I looked up the parts - so far I find the need for ventilated blowers (driver and passenger side), new switch row (where heated seats, parking sensor, fold seats, rear sun shade, etc. are located), and a new plastic trim piece to accept the new switches (it'll be a longer rectangular opening than my existing set).
I assume all wiring is in place to make this plug-n-play...perhaps a module or two will be required. Just looking for advice if anyone has done this. From the parts websites, OEM, it looks like about $1000 to buy it all new...although I may try used from a wrecked unit to save $$. I haven't had a car w/o ventilated seats in a LONG time...can't believe this car doesn't have them. My 2007 Range Rover and 2012 Ford Expedition have them...but not my 2014 MB!
Guess you bought the car used.....it's an option.
If you can get the parts at a yard I bet it's still more than $1K - but worth whatever the cost if that's what you like/want.
I know it's an option - otherwise this thread wouldn't exist. Hell, my 2012 F350 truck had them. It's becoming pretty hard NOT to have them. Just hard to get used to warm seats.

I doubt it...unless there's something massive I'm missing. Blowers, switches, modules, trim plate...that's all I see in the diagrams. And my prices are through a MB dealer @ wholesale, which is available online to anyone.

IMO it's just as useful as the heated option although the heating is stronger when compared.
I would much rather add the dynamic seats and forget about the blower. That's pretty much the only option I don't have and wish I did. I'm sure the cost and effort would be outrageous. Automatic trunk closer would be nice, but not really a big deal to do it by hand.
The massage seats, on the other hand are excellent.
At least on the Infiniti, they were mildly noticeable. If you were wearing a dress or pants, forget it. And that's on the Infiniti where they had a Peltier-element heat pump in the seat, not just a fan as Mercedes does.
I was SO excited for ventilated seats, but my bubble has since been burst. It was a "must have" in my buying criteria last year. Silly me! Today, I wouldn't pay more than about $1.98 for them. To hell with the $1k estimate from the OP.
Most autos seem to have poor ventilated seat perf excepting those with true a/c seats with a dedicated a/c condenser or something, like the Lexus LS460 and similar. Maybe I heard some Ford products have good ventilated seats, but the point is "buyer beware."
