It has a quiet, smooth as silk ride and handles well, taking turns much better than my 2000 Chrysler Concorde LXi. I only have 3 complaints, although they are minor. The rear passengers complain that they have no room for their feet, as the front seats are low to the floor. Second, why can't the Japanese make seats comparable to those in American cars? My Chrysler seats were much better padded and roomier. 3rd, Toyota Sienna is much better appointed with tiny things that make a difference, like a little hook you can flip out to hold a garbage bag. The Lexus doesn't even have a compartment for sunglasses, which even my husband's Sentra has. For $38,000+ I expect more details.
Love the sideview mirrors, which rotate down when the car is in reverse to help you see behind. Also, the automatic lights and wipers are cool.
Make the seats a bit roomier and better padded. Give more room for people's feet in the rear. The control panel is bland and add more touches, like a compartment for glasses and a place to hang a garbage bag. Fix the front console door so it doesn't open accidentally everytime it's touched.
