BMW has no balls and no interest. The argument that US won't want to "lose luxury" is such BS, I wonder who at BMW does the NA market research. How can't M3 CSL/GTS/CRT sell in NA if it is one of the largest BMW M markets?
Anyway way, BMW has to bring a final M3 CSL/CRT/GTR what ever they call it, even if overpriced, because the first and last V8 powered M3 must be celebrated. Unfortunately they did not do that with the previous M5/M6 which is one of the best engines BMW ever built.
