Two days ago, I took delivery of my seventh, new LS. My first was a '93 LS400. I have since had a '96, '97, '00, '03 & '05. All of my cars have had the air suspension, including this new LS460L. This is, BY FAR, the smoothest, quietest, most magnificent car I have ever driven or ridden in. My '97 was my previous favorite, as it had 16" wheels, which I happen to feel is the size that should still be used. My '05 LS430 Ultra had 18" wheels and I was quite unhappy with the way it rode over bumps. On smooth roads, it was wonderful, but the low profile tires just don't offer enough sidewall cushion for me. To my surprise, this '08, with 18" wheels, soaks up the bumps SOOOOO much better than my '05. Still, I wish the car had 16" or even 17" wheels, as I feel it would ride that much better.
