W211 grey cooled seats

[blitz500sl]

Hi guys I'm looking for a driver's seat or passenger and a complete rear seat from a estate in grey leather from a car equipped with ventilated cooled seats that has the perforations on the outer bolsters. I can use a front seat from a saloon also.
I believe the colour and leather is supposed to be AMARETTA/LEATHER/NAPPA/SEMI-ANILINE - GRAY

I'm in the UK
Thanks
