[SoapBox On] WTF was BMW thinking in including the asinine "greyish" diffuser on the M850i models? Plus adding insult to injury for those that paid for the Carbon Fiber package and yet the "greyish" stupidity still wraps the diffuser. [/SoapBox Off]
That said with COVID-19 in effect I've not followed up with my detailer on wrapping the "greyish" stupidity with either a match to the Shadowline trim or carbon fiber components on my M850i. However, once my detailer is back in the game I'll have the rear diffuser wrapped to negate the "greyish" stupidity. Right now I'm leaning towards a Shadowline match as the only external carbon fiber is the roof and mirrors. No matter which direction I take the asinine "greyish" diffuser will be history.
