As the first person who mentioned sound said: it's all subjective. Many of us didn't like the sound of the V8 as opposed to the I6 in the E46, but the E92 spawned a generation of M owners that love the sound of the V8. Likewise, I'm sure there'll be people who love the sound of the I6 with turbos.

I personally don't know what the fuss is about. Don't most M3 owners change out the exhaust because aftermarket exhausts that are available tend to be much lighter and sound better anyway? I don't like sound of the stock GT-R but the Password JDM exhaust makes it sound like pure sex. And with the market for M3's/M4's being as big as it is, we should expect a variety of different exhausts suited for everyone's taste.

There's only one thing I'm worried about, and it's reliability. The first MY of the M5 had its issues and required a recall IIRC. I'm hoping there won't be any issues with the M3/M4.
