A used car sales/dealer could have owned it for the short period. And only driving it when needed, or a few times around the area for potential buyer test-drives. It could have also been a second car, or belonged to someone who drives very little, or belonged to a student who went away fro college and came back with a more preferred vehicle -- notice how the registration location stays within the same general area.
One of my cars currently gets less than 3,000 miles a year put on it. it is garage-kept and is parked next to a 2011 motorcycle with less than 2,000 on it. The car is currently at 68,000 for being a 2001. So there's also that.
You are doing the right thing by asking a lot of questions.
