A foot is a lot for a car, are you kidding me? Go drive one - heck , any 5 series these days, and tell me you don't think it's big.
Haven't driven the M5 but did spend 5hrs with the CTS-V wagon. It is big but it doesn't feel like a bus. There just isn't enough of a delta in my opinion to say that comparatively the M5 (or CTS-V wagon) is bus to our M3. It's not like getting out of an Exige S240 and into our M3 kinda eye opening difference.
Just my $0.02.
