So I spent around 7 hours in the car yesterday, A14, A1, M25, M4, London - North circular, M11, A11, A14 and saw my first IS300h on the road - right at M25/M4 jct heading anticlockwise - dark grey colour F Sport and looked very M3 like as it went by (I was going onto the M4) from the rear as the different tyre widths were obvious.
Very refreshing that in all that time I only see 1.. No doubt this will change as we all get our cars..
