Yes...a second 'thought' as a new owner of this Mars Red cabrio.
From my searches of the forums, it appears that E550 sedans had the heated steering wheel option for 2014...but it was NEVER(?) an option on the coupes / cabrios.
I would not be looking to 'DIY' this job, but if you have successfully made the change TO a heated steering wheel on a 2014-2017 E550 cabrio, about what was the 'all-in' price?
