Replacement Roof Trim - R231 SL

[TicTax]

Hi Folks - as can be seen in the picture, the trim on the rear left of the roof on my R231 SL has gone AWOL. I'm assuming this is cosmetic rather than functional but does anyone know if and where replacements can be sought? I haven't had the chance to contact Mercedes themselves yet, will do that tomorrow.

Thanks in advance for any and all suggestions/help.

it must have come off. Perhaps in the boot?

Possible.
