Smashed passenger side mirror on my E350. The casing is broken too and I am looking to replace both.This seems like a simple DIY task, now that the whole assembly is exposed and especially since the dealer is quoting 1.5K to fix it.. I am looking for help from experts here on a couple of things.

1. What is the best place to get replacement parts? Search on autozone, Amazon and ebay didn't yield anything helpful. I am looking for heated mirror with blindspot sensor. The one I have is Gentex mirror that has part number 930-0018-001 (at least that's what I think the part number is).
2. Should I replace this as the full assembly or individual parts? Assemblies I found required paint job which I am trying to avoid.

Thanks for the help!

 

VIN? I will PULL part #s from EPC. Replacement trim will be painted to match vehicle. Depending on damage may be cost effective to replace parts. You can start here to comparison shop:
