The wheels are modern knockoffs of a wheel that was introduced in the late 1970s and often put on the 3.0CS. They looked incorrect then. They are incorrect now, even in the right size.
As for the E9, there is one being auctioned off in Palm Springs in two weeks. It's a 1973 painted blue (not an original color) which was supposedly in the Crevier museum until 2011 and which has about 66,000 miles on it.
I was interested, but it's an automatic, and that transmission is very weak. Plus the rocker panels rust like nobody's business. I tried to get a pre purchase inspection at a nearby shop and was turned down. I figure it would have cost me about $35,000 to bring it back to original. And the auction house says it will go for $45,000 to $50,000. I suspect $30,000 is more like it.
But I passed. If I can't get it inspected before I drive to Palm Springs for one car, it's not worth it.
