I bought a new 2005 Avalon last year (my first experience buying a Toyota) because I had heard such wonderful things about it and the Camry. Boy, am I disappointed ! The transmission is horrible. It "bucks" when accelerating from a stop or slow driving. I was told that it needs to "learn" how to behave from the driver. During one service appointment, they "untaught" it to see what would happen. No change. My kids get car sick, it's so bad. The dealer told me to keep checking with them for a "fix". If there is no "fix" soon, I plan to get rid of it while it's still under warranty so it will have a good selling point.
Roominess. Smooth ride on the highway. Sleek looks. Safety features.
