UPDATE:
Spoke this morning with Lexus Dealer, seems that the new Cat isn't coming from somewhere in Europe, but rather Japan!!! So no car for another week.
They are however lending me a car again this weekend so my weekend break to Windsor isn't spoilt, so thats very good of them.
Steve has summed it up, my Old GS was bullet proof......they just don't build things like they used to, not just a Lexus thing, i'm sure many Merc and BMW owners would say the same.
Ho-Hum.
