Andy, quite right, I remember you had to sort of concerntrate when pressing the button to notice it.
Must say, that is one of the best things about the GS, it handles so differently, must be the gearbox over the rear axle amongst other things. I always found the 3200 very twitchy, dont get me wrong, luv mine to bits, but you do notice the vast improvement when you get into the the late cars.
