I'm new to C6s. We are considering purchasing a 2011 Supersonic Blue Grand Sport with 37k miles. One of my concerns is that the rear bumper paint does not match the body paint, please see picture. The car appears to have been taken care of and shows a clean car fax, which I know doesn't record all accidents. I've never closely examined a Supersonic Blue car before so I'm not sure if this paint difference is normal over time (like the rubber bumper C3s) or signs of a repaint / repair.
Also, the car had a front license plate bracket installed by drilling holes in the front bumper. Are there "plugs" available or some other fix other than filling the holes and repainting the bumper?
That is not normal. Something has happened and the bumper got repainted. Either that, or someone on the GM plant mixed the wrong paint code for the rear bumper. Get a GM VIS report from a GM dealer nearest you with the VIN number. The service dept will do it for free. That report may show something about that bumper.
Good Luck
a little paint work shouldn't be a big deal. Plastic bumpers require (or should) flex additive, a body should could have made a mistake on a simple repair.
Hence car was hit in the back and was not repaired correctly (any true repair shop would have color matched the rear bumper to the car during painting it).So what you have her, is someone picked up a blue rear bumper off another car, and was not the same year true color match to the car years blue it was put on.
Also, will bet that the History report.car fax report you get will show no wreck on the car, making you really wonder what the damage the different color blue used rear fender is hiding in the fender void area since the work was done under the table without being reported.
The rear fender is just a flimsy cover, and the rear structural part of the car is hidden under the cover.
Knowing a few things about paint, I want to point out that when you have metallics in the color, they will lay down differently on plastic vs other materials. This is due to the electromagnetic properties in plastic. Sometimes the metallic particles will stand up or lay down depending on the material it is sprayed on. If you look closely at any metallic paint direct from OEM, you will see slight differences between the bumpers and adjacent fender / quarter.
Only saying this to let people know - don't assume the vehicle has been wrecked. You can easily look at the structure underneath the car to see if it has been repaired. In this case, the color appears to have been redone, but it could have just had a scratch on the bumper.

It's a poor repair, but there's a silver lining. They haven't done any blending, which suggests the fenders and hatch are as-was. In other words, the (paint) damage was likely isolated to the bumper cover.
Car color is supersonic blue (slight purple tint to it).
The rear bumper is off a car that was jet stream blue.
Hence when a shop orders a new replacement bumper, its not painted, so they grab the RPO code off the car, and paint it that color.
Granted may not be a perfect match since the flake may not lay the same way, but is going to be a better match that a rear bumper off another car that is not the same color to start with.
