[Not-EWRX]

The Porsche and Subaru boxer motors share oil leaks and poor access to spark plugs. Alfa has them beat on the oil leaks though -- I wonder if that means Alfa made the better boxer motor?

I think it's funny that someone could consider the boxer motor rare, since many millions of vehicles use one. The 2CV and Beetle alone would probably make it among the most popular motors in history, and that's not counting other VW and Citroen models or even Alfa Romeos etc.

The Wikipedia article does not find the Ferrari boxer motors noteworthy, for reasons only they can explain (my guess is the author may not have known how many "r"s in the spelling). On the bright side they do mention one of the two most important boxers in history -- the Citroen and the VW that were in production for many decades. It's also interesting that Honda and BMW make among the most popular boxer motors -- although the BMW fans know this and get excited about it, many Honda people have no idea.

Honda with a boxer Were is the proof
