More Fun than Comfortable
 While I love driving my 4.6IS there are times that I wish I had bought the 4.4 in hopes that it would be a firm and sporty suspension without riding like a corvette (but it's great to be able to keep up with most sports cars).  The 4.6IS is incredible fun, awesome styling, and full of luxury.  My only criticism is that it doesn't ride as smooth as my Lexus LS400 I traded in for it (no surprise there).  I would buy another one tomorrow...
