Traded my 2003 Seville, not disappointed at all. The gas mileage is great on regular gas. Nav system leaves a little to be desired, that message gets on your nerves every time you start the vehicle. Should be easier to program. Sound is good JBL did a fine job although I did a personal upgrade surround sound is a great feature, Cabin is tight noise and rattle free. I bought 3 caddys before I purchased my Avalon. When it comes to comfort, it's a no brainer. Avalon wins; wheels down.
The ride is smooth, the sound system is good for a factory production. Backseat is cool, I like the flat floor as well. Styling is upscale looks good in the driveway.
