ha ha! what rubbish! The is200 values have been plummeting like a stone for months!
When i got out of mine last summer it had depreciated £7500 in 8 months (from new). I checked Glass' guide and the resale price was correct
The new one is very much the successor to the old IS and although some bits are totally different, like the rear lights, a large part of the car is evolutionary.
Looking at the car last week in Geneva i noticed the front wheel arches are very similar and the front profile of the car is similar too.
Those tricksters at lexus!
Also, the car only looks 10% better in the flesh - maybe a different colour and seeing the car in the right context, ie: the road and not on an angled, rotating pedestal thing would do it justice.
