Just traded in my 2003 SLK320 (R170) for a 2013 SL550 (R231). Couldn't be happier.

While not technically "Under the Hood" (it's installed behind a panel in the trunk) I installed a Mods4Cars STHFMZ3 SmartTOP Roof Top Control module. It makes the vario roof operate the way it should: one touch up/down from the console switch even when the car is moving, remote open/close via the key fob, one touch windows up/down, etc.
