Of all the cars I've ever owned, my Camry has been my favorite. I've kept it longer than any other. After 13 years, it still gets great gas mileage and runs great. I plan on buying a new one this year just for a change. A friend of mine wants my "old" one. You can't go wrong with a Camry.
Favorite features are gas mileage of course, looks, rides smoothly and one of favorites is not being able to lock keys in the ignition.
I'm sure it's been done but my seats could be a little more comfortable, cup holders adjustable and a place to rest my arms when I'm the passenger.
