Hubcaps and cars

Speaking of my auto-smart son, he is noticing hubcaps these days. Every day, on the way to school, he notices this van parked in a driveway that has three different kinds of hubcaps on it. Every day he asked me why they "changed the wheels". (Wheel-changing is now in his paradigm as we recently went to Goodyear and had the tires rotated while we watched). Every day, I answer that they didn't have enough of the right kind of wheel. He says, "Oh," as if that answer completely satisfies him. This repeats daily, or multiple times a day (we go to school 3 times daily).

He also can tell me which one of our friends' cars a particular hubcap matches. "That wheel is like Miss Donna's wheel," he'll say. He can also identify makes and models of cars, regardless of color. Of course, he doesn't say "Impala", "Accord" or "Taurus", but "Mr. Bower's car", "Nana and Papa's car" or "Miss Donna's other car". I'm not sure what to make of this. It's like having a car Mozart :) Don't think there is much money and fame for a kid who can identify cars at a young age. But it's pretty cute, nonetheless.
