I found my GS450h shortly after your post. Picked up an 07 plate with 52K on the clock for 12 grand. Cant go wrong when it came from a Lexus Main Dealer with full 12 months Lexus as new Warranty.
I cant get enough of this car, it is a thrill to drive and gets nothing but compliments and praise from freinds and strangers. Even the guys at the local Valet and car wash company wanted to take it home for the weekend today when I asked for my key back.
