I've had, CT's, IS's, a GS F sport, an RX and an NX now as courtesy cars from Lexus Hedge End. They had an LC in the showroom yesterday but wouldn't let me take that! I'm picky about my spec too and when I wanted to trade in my IS 220 I was looking for an IS 300h Premier in Mesa Red with cream interior but they never had one. However, they they had a GS Premier in the right combination and I was sold. Best decision I made. Such a beautiful car to drive. I found the NX too jiggly with hard suspension but without the sure footed handling to match. The GS on the other hand wafts along in ECO, Normal and Sport modes and handles really tightly in Sport + but still with a pliant ride. With regards to rarity about a month ago spent a week driving up to and around Scotland and only saw three other GS Mk 4's. Just got back from a week in France and didn't see any!
