The Sienna was new when we bought it, and it has all the major options, which means we paid top dollar. We love the navigation, entertainment and other conveniences that make traveling with our kids easier. The kids ride in car seats though, which could explain their comfort. We recently took our first long-haul trip and had the aching backs to prove it. Never again! We had intended to keep the Sienna for perhaps a decade, which is why we went for all the options and didn't mind the price so much. After all, Toyotas have a reputation for lasting. We are getting rid of it, however, because it handles terribly in the snow.The Sienna literally gets stuck in two inches of snow. What a nightmare!
Power sliding doors, power liftgate, and folding seats. Built-in sunshades with the entertainment system are also nice. The nav and bluetooth features are nice, if pricey, options. The adaptive cruise control is nice too. The vehicle accelerates and shifts smoothly. Acceptable gas mileage.
Improve drivers seat comfort. Improve performance/traction in inclimate weather. I am so sick of getting stuck in as little as two inches of snow that I am getting rid of this vehicle after only two years; we had intended on keeping it much longer.
