hey sandman.
continuing to enjoy your thread.
hope all is well.
i am biting on your question about car wheels looking so similar...
i think the 'classic' design of 5 spoked wheels is one reason. i personally like 5 spoke wheels. porsche has been using a variant of this fundamental design since the 1950's.
some may call it conservative, or even boring, but i really like it. i pretty much have always had 5 spoke wheels on my cars. i really like that the wheels 'age' well. i cannot say that about some people's aftermarket wheel choices.
the 3 examples you posted are all basically 5 spoke with a tad of variation in each.
anyway, keep-up the good work here.
safe spirited driving to you!
