I moved into a GS430 from a GS400.
Better Nav and sound but no more
tiptronic transmission. I attribute the
diminution in throttle response and tip-
in response to the different tranny and
possibly gear ratios from the 400. I
have to stomp on the go pedal to get it
going. GS400 more responsive and fun to
drive. After the lease is up, I'm
looking at the new Infiniti M45.
bring back the tiptronic tranny and
better gear ratios for better throttle
response. This thing is a slug.
