When I was a kid and as my dad drove down the road he'd occasionally quiz me as to what make and year a particular car was. I enjoyed the exercise but would imagine this would be a very difficult quiz today, especially figuring out the model year.
My brothers and I played the same game a lot. That was back in the sixties when models changed yearly by a noticeable difference. Today I have to look at the grill emblem sometimes just to tell who made the generic thing.
