Regardless of what any figures say, the Saxo VTR and VTS will be much faster, so will virtually any proper hot hatch. IS200's are reliable smooth comfortable family cars but also big, slow and boring. Rubbish on petrol and very impractical for a big car too. If you want something fast and fun or a drifter don't buy one, simples.
I'm not meaning to sound negative, but if people take their rose tinted glasses off I'm sure they can see the limitations of it.
