“If it ain’t broke, don’t fix it.” That’s sound, if not particularly articulate, advice. Advice that Toyota claims it has ignored for its complete redesign of the sixth-generation, 2007 Toyota Camry, which was unveiled at the 2006 North American International Auto Show in Detroit. But in reality, the company has taken it to heart more than ever.

The Toyota Camry ain’t broke because it’s the best-selling midsize sedan on the market. In the years since 1983, when the Camry first arrived in America, it has proven itself a dependable mode of transportation, constructed of quality materials yet providing value to the car’s 6.5 million buyers during its 23-year lifespan. The one thing the Camry isn’t, according to Toyota spokespeople, is exciting.

To combat the Camry’s tendency to induce naps, Toyota is trying to shake things up with the redesigned 2007 model. Toyota says that the styling pushes the envelope, but the important thing is that like each of its predecessors, the 2007 Toyota Camry is a car you buy today, drive for 10 years, and sell without concern that it’s going to go out of style. And it’s likely to retain a healthy chunk of its value, too, especially if you follow the scheduled maintenance intervals.
