I speak with many wheel customers. Black wheels aren't necessarily an age related thing, it is more of a racing inspired or high tech thing. Many racecars out there run black wheels. Chrome is actually becoming less popular, it seems. Many of the old school hotrodders won't have anything but chrome wheels, and these are the guys who tend to dislike black wheels.
However, send your Dad this photo and tell him he is wrong. The first cars had black wheels too.
