The Toyota Corolla is the best-selling line of cars in automotive history. Corollas are known for being inexpensive, reliable and fuel-efficient. More than 200,000 Corollas are sold in the U.S. every year. The Corolla has gone through several generations since its introduction to the U.S. in 1968 -- each new model has incorporated changes, ranging from minor tweaks to total overhauls. The 2005, 2006 and 2007 model years were all part of the ninth generation of Corollas, so the differences between them are very minor.
Trim Levels
The 2005, 2006, and 2007 Corollas are all available in the CE, S, and LE trim levels. CE is the basic model, but it still includes a few amenities such as air conditioning and a CD player. The S trim is a step up, with a rear spoiler and smoked headlamps for added style. The LE trim is the most upscale version, with faux wood interior trim. A fourth trim, the XRS, was produced in 2005 and 2006 but discontinued in 2007. The XRS features a sportier engine, alloy wheels and upgraded brakes.
Engine
All three model years are built with the same four-cylinder engine. The 2005 version is rated at 130 horsepower, while the 2006 and 2007 Corollas sport a 126 hp engine. This is due not to a change in the engine, but to a change in the way that the SAE calculates net horsepower.
Leather Seats
Leather seats were available as an option for the higher-end Corolla LE. Toyota dropped the leather-seating option in 2007.
