I bought a loaded ES350 with 30,000 mi, car was about as perfect as you could expect with 30,000 mi. Hway MPG about 32 (amazing). Quiet, very comfortable, great car for trips & around town and handles better than you would expect from the reviews. Not a sports car (I already own one) just a beautiful, comfortable car & ride. I have owned Acura's & Infinity's, this is the best.
Comfort, Quiet, Fuel Economy, and the automated options like auto wipers, parking sound sensors. Beautiful interior, cooled seats are nice.
It does have a slight rattle over bumps in the dash area, car still under warranty and I expect this will be corrected when I bring it to the dealer.
