Does anyone know where to find this replacement part? The parts I've found on eBay/Amazon or ordered have all been an incorrect fitment as they go straight across instead of as indicated by the red arrows in the attached photo.

I've seen the part sold on eBay and Amazon under different names, usually listed as rear bumper diffuser or valance but I'm not sure what the OEM part name or number is for the correct type of fitment that I need.

None of the diffusers or valances I've been able to find fit the style of bumper on my 2008 C300 Sport.

Thanks for any advice. If I can't find anything here I'll just take it to the dealership but was trying to avoid the trip and cost.

That's because that's not a 2008 rear diffuser...that's a 2012+

So either that's not your car or it was in an accident or something and replaced with a newer style rear bumper.

Well I guess that makes sense then. It is my car, but I've only had it since January and the Carfax report didn't show any accidents or repair work so I guess I found out the hard way.

Thanks for the help.
