defalt

Hello
Does someone have a list of all the options that could be purchased on W219s ? The seller of mine told me it was maxed out, but it is definitely not:
I am missing:
heated steering wheel
heated rear seats
rear electric sunshade (rear windscreen only, was it available on the doors?)
power closing trunk
massaging seats (front)

Was it possible to get power rear seats? What more?

Thanks
