I upgraded from a 2006 Corolla to a 2010 Camry and after driving the Camry for about 10 days I feel that I never want to drive the Corolla again. The overall ride quality is great, very quiet, very reliable, acceleration for a V4 engine with 6-Speed Auto is great, Felt like you have a V6 engine when you step up on the gas. Brakes with ABS is good, the stock sound system is pretty adequate for my needs. Overall very happy with the car. So far the only thing I don't like is the mileage, I was used to the Corolla mileage so it might take a little bit of time to adjust to the mileage drop with Camry, but I don't regret the drop in mileage any bit.
Styling, V6 type acceleration from a V4 Engine, ABS, Roomy Interior, Power Driver Seats, Remote Trunk Release.
Toyota should keep trying to increase the mileage as much as possible.
