Stuart Truman said:I've not done anything more scientific than test driving both. The M "feels" quicker, but the power delivery from a 3.5iS on full chat is immense.
Mine does well on the track and surprises a lot of faster cars with it's handling kicking ass on the corners. Understeers a little but only at the start of the corner.Stuart Truman said:3.5iS 0-62 is 4.8 seconds, so slightly quicker than an M in a straight line. I wonder how they'd both fare on the top gear track :?
