Well done swamp2!
I think the purpose of your work is achieved. That is to make people on the forum actively discuss the argument. I also like the bracketing stuff. Finally someone who doesn't pull out exact numbers predicting future with some crystal ball...
I also agree the V8 in the M3 will die with the current M3 and speculations about a V6 are nothing less than absurd. A V6 form a company with the longest I6 heritage in the world?? It's since 1917 they've been building them! It will be ether a heavily revised N54-55 or a new I6 multi-turbo engine IMO.
Good job swamp2!!
