My car was rear-ended and totaled, I kept the salvage title. I've been lurking LKQ and car-part.com in my area but can't find the exact cover I need (facelift Mercury metallic with parking sensors, rear). I can buy a new one from Lexus and have it painted at a body shop, but the price is steep. Any other way to get a hold of bumper covers already painted?

 

Search for body parts at the Lexus recyclers. There are several in CA, including a few outside of Sacramento, for example.

I've been looking / waiting for a face-lift LS430 in silver w/ a non-damaged from bumper to show up in local salvage yards for years now, still waiting...
