Very interesting ... looks like the GS430 is not in desperate need of AWD after all. I guess the only complaint about VDIM is that it stops you from pushing the car to it's limits ... and it can't be turned off, as far as I know. But of course, you can always get the GS300 AWD for more fun driving

. I guess the ability to turn off VDIM would be icing on the cake

VDIM totally makes sense ... Lexus is not trying to follow the Germans ... Lexus is going along it's own path ... and setting it's own standards. Toyota wants Lexus cars to minimize all the bad and dangerous aspects of driving while maximizing everything else. VDIM has gotten Toyota one step closer to that ideal. No doubt VDIM is a very advanced system that's safer than any German system, including Quattro, or Mercedes VSC.
