This is my second LS series. This is by far the most comfortable automobile I have ever driven and I have driven hundreds. I purchased the Ultra Luxury Package this time and the amenities and ride are absolutely unsurpassed. My wife and I drove to Florida last summer, 2700 miles in all and the level of comfort could not have been better. There are copiers, i.e. the 07 Big Mercedes and BMW's,but they don't quite compare the the ride, reliability and comfort of the LS 430 Ultra. Superb motorcar.
Steering feel. Adjustable suspension. Power, quick but not a performance car. Laser guided cruise control, it will actually slow the car down if there is a vehicle in front too close for the speed. Navi system is nice touch.
None, great automobile. I have looked at the 07 but do not like them enough to trade at this point.
