Just purchased and have 6000 miles so far. The car is everything I expected. Test drove MB, Infiniti, and Acura. Silky smooth, quiet, powerful, and comfortable all describe this car. Even the exterior design and look has compelled onlookers to offer favorable compliments. It's not one thing in a Lexus, it's the total package thats makes it a great buy.
Navigation system, bluetooth, overall ride and comfort - just fun to drive.
