I bought my '13 used and it now has 70,000 miles. It doesn't have a single panel without at least 1 rock chip; you can see primer on a few spots on the hood. Maybe it's the black that makes it look worse, but I have never seen anything like it.
It's 5 years old, that's going to happen after 5 years and 70k miles. Yes, being black makes it look worse than it would on another color. The paint on my '14 is better than my previous Subaru, and Chevy's.
