Here is the part number for the OEM armrest from their accessories catalog. A4519701601 - apparently if your smartie doesn't have the armrest you can add it easily because they only use one seat frame for all their cars and it is designed for the armrest to simply bolt onto it once the seat cover is pulled back a bit to expose the frame. I just bought a 2014 electric and the website says the armrest comes standard NOT AN OPTION. The reality is the armrest is an OPTION because without the armrest, there is a small storage pocket right where the armrest goes. So the dealer is honoring the website and supplying the armrest and installation at no cost but they have to pierce the pocket (which I don't use anyway) to install it. Once it's done I plan on posting some pictures so stay tuned.
