Hello, I'm pretty new on here so forgive me. Just buying a nice E320 cabrio, but doesn't have heated seats. I was hoping to source from a main dealer the heating pads to go under the leather, but am being told not available as stitched into leather. Anybody know if that is right and if not the part numbers? The loom and switches looks easily available on German ebay, but its a headache trying to find a walnut centre trim for the cabrio with holes cut for the heated seat switches as well as all the other holes needed. Anyone have one ( miracle!) or know anyone who can cut the holes- I don't trust myself with a dremmel . Also know of any good trimmers in my area-Bristol- to take the seat covers off/on?
