A set of Ferrari 275 GTB magnesium Campagnolo wheels with period tires sold for only 1875 USD, and these 3 GT40 magnesium rims went for 750

I would have guessed they would have went higher... but, I suppose there just aren't a whole lot of people showing up to an auction for Ferrari rims for a 275
