Teach them how to be cool early on.
Among car fans, the German engineering is legendary. That's why BMW fans tend to be very very VERY into their cars. They like the ideas, they like the design, they like the reaction, they like how people look at the brand and say "Ooo. Quality." Is that going away any time soon? No. No, it's not. Teach your child that we live in a world where brand is important, and teach them early.
