yes it really was quite comfortable at normal city speeds, no big sounds, but when the accelerator goes down you are really overblown by the amazing BMW V12
I have had a ride in F40 once but that is much louder on lower speeds, a lot of rattles and cracks are heard which the F1 does not have. Only the sound of gearchange and acceleration. The V12 is not blowing your ears of though. I think you can even cruise with this car from London to Monaco and you won't be tired.
