When I sold my fox red M3 seats, the buyer needed my black 335i door cards also as he has the cinnamon brown seats and doorcards.
I had some rear M3 doorcards in storage for years now (never found a cheap front set pop up for sale) so had to buy a set. Thanks to socket we went halves in a M3 interior (he got the seats I got the door cards) and I started to fit them up recently.
The M3 doorcards are exactly the same except they use higher grade nappa leather which looks really nice (I'll miss the M3 seats!) and have the silver speaker grilles (optional upgraded speakers from standard had silver speaker trims)
The M3 doorcards were missing the seatbelt butlers, so I transferred them from my 335i doorcards and the speakers from my 335i (I have L7) and installed them to the trims.
Since I wont have any rear seats, it will probably be cheaper to just buy a M3 rear seat rather then do a custom rear seat delete with alcantara and save 10-15kg (exhaust is boomier also with rear backrests gone)...
The front door trims should arrive this week hopefully
