IWDOTH: The current trend of grey cars all just look like they've been base-painted with primer ready for the actual paint color to go on

Some other offenders:
Nardo Gray is a good color, and basically every car's body lines are easily defined in the color. Its pretty hard to find a car that looks bad in Nardo Gray.
It originally was a special order color on the 2013 Audi RS7, and ever since has had various other manufacturers offering similar colors. It's a bit like Grabber Blue, but since it is gray it has a little wider appeal.
