I have waited for a car like the GS for many years. I love the LS but it has always been a little too big and reminds me of an old man/womans car. The old style GS was close to the right size, but I never liked the styling. The 2006 GS has it all great styling, great engineering and comfort. The V6 is quick and at the same time gives the owner great gas mileage. It is well equipped, even the "base" car has all of the luxury item that one would expect. When I am in the cockpit I feel like I could go to the moon! WHAT A CAR!
The styling is exceptional and the performance is outstanding. It is also so much fun to drive that I find myself inventing reasons to drive it!
The only improvement that I can think of is the trunk size, but it is really adequate.
