Bob you make me laugh! Seriously it's just for fun. I generally can guess years on cars given 4 choices of which is the oldest and newest. But when it comes to knowing kaisers and hudson, etc.. that were made before I was born it gets more challenging. Mostly I think we know what we grow up with. In my case being born in the early 60's by the time I hit high school they were the cars that were cheap enough for us to buy and fix. So I'm much more familiar with them than the cars of the 50's. I just figured for car buffs out there that this would be fun. It definately exposes you to some models you may have never heard of!
