While I agree that the M branding isn't what it used to be, some of you guys forget that the 2800lbs E30 M3 wasn't considered light when it was released. It was full of state-of-the-art electronics of it's time. My 2000 Celica was a bigger car yet 200lbs lighter than the M3 that was 10 years older. Compare a 911 from today and the 80's and you'll see the exact same trend in weight, comfort, and technology.
