With the sport suspension there is no Buick/Lexus wallow or lean, one can hussle on mountian roads. Some harshness on bumps with the 45 series. Chasis is vault solid.
Brakes are easy to modulate in quick stops, feel powerfull. Like the numerous airbags.
Built like a vault, no repair/failures. Only gripe is battery discharge after 4 or 5 days not running.
Too quiet, wish for more V8 sound. Mark Levinson is better than my home system, tho.
