Here's a crappy pic of a grey one spotted in the wild. I think this was Warrensburg, MO Walmart.

AND, this is the much more exciting part, I found my long lost sister!! I don't think I've ever seen another pink one in the wild. I had to park next to it temporarily just to get this picture haha.

I also saw a black one driving in Kansas City that I was not able to photograph. So many!
