Carl, with all due respect, it's somewhat ironic that you accused the other poster of being unhappy and impolite and then call his post nonsensical (not exactly polite) while being unhappy about the name change.
I agree with him that the number or even the M badge doesn't matter as long as it drives like one. A rose by any other name would smell as sweet. M nostalgia is nice but at the end of the day, it's how a car drives that's the bottom line.
