I bought the Avalon with 14k miles on it through auction and have LOVED it ever since. Now has 215,000 miles on it, gets 26-28 mpg, runs smooth, quiet, and is a classy drive. Passengers like the big back seat, lots of trunk space, carries 6 when needed (bench seat), can't say enough about what a great car this is. I spent a little extra to get really nice sound system installed by Toyota. I use good gas and religiously change oil/filter and have checkups when due. Toyotas are the best and this Avalon is their pearl.
Smooth, comfortable, quiet ride; great gas mileage and reliability; classy.
Wish the back seat could drop down to carry big items. I probably would not have bought a Lexus RX as a second car if had this feature in the Avalon.
