I've had to sell my GS purely for practical reasons (I needed a large estate). I've ended up with the Audi A6, not because I particularly wanted one, but because it had all the features I was looking for, and was big enough for my wheechair, etc. in the back. My GS really spoiled me and limited my choices, since most estates just don't have all the classy features that Lexus supplies as standard.
Mind you, the Audi is superb and the quattro drive gives me peace of mind :) :)
