Even with a 4cyl the Camry still has plenty of power but can react slowly. As one would expect, I have had no problems with the car except for low pressure in one tire. Getting actual mileage around 26 highway (set cruise - 50 miles round trip) and 18 city during first 1k miles. I think this could be due to the automatic transmission slipping.
Plenty of room. I carpool to work with 3 other big guys and everyone is comfortable even in the back seat. Smooth and quiet ride.
As a tall guy I can not find a good adjustment for the driver seat head rest. Fuel mileage is not as good as expected. The Camry can take a few seconds to react when you push the gas.
