Crumbs, what a welcome :)
I do like big cars, normally aspirated muscle over forced induction anyday! I'm very very happy with the GS, I think it's going to be the first of many; I loved those Scorpio's too mind, it was my third Cosworth (one Granada and two Scorpio Ultimas), for what I paid they were terrific value.
The Lexus is a very different though, it is so solid and refined. Remarkably good as the Fords were, after some miles they all rattle and start to fall apart, also the technolgy in them was quite new for Ford so reliabilty of the gearbox and other bits and bobs is a problem for a lot of them now. The Lexus feels like it will run forever as long as I keep it serviced.
