The theory of evolution as applied to small Japanese cars:
Today's Corolla is nicer than yesterday's Camry.
Especially the top-of-the-line XLE sedan. Base price $17,550...buying as standard equipment what used to be Lexus-type options (six-speaker stereo, power everything). The tester I had added an upgraded audio system with Bluetooth, 8 speakers and steering wheel controls, an all-weather package and a set of floor and trunk mats. Price with delivery charges: Still under $20,000. The EPA says 27 city/35 highway, which vaults it into TireKicker's Top Ten Fuel Savers.
If you're trading a six-year old (or older) Camry, this Corolla will feel like you're trading up nicely.
