With wide price ranges and numerous body configurations, this diverse segment has two clear Best Buy choices--the refined Lexus LS 430 and the unique Audi A6. The LS 430 can't be beat for comfort and features at around $55,000, while the A6 earns Best Buy status for its blend of space, performance, design sophistication, powertrain choices, and workmanship at prices below those of most rivals.

We Recommend the Acura RL--a steal at around $45,000 fully equipped. Though it is a front-drive V6 in a field of V8 rear-drive models, it has a great ride, plenty of power, and is quite luxurious. If you are looking for something a bit more sporting, we Recommend BMW 5-Series. If your taste ranges more toward the luxury end, then take a look at the roomy Cadillac DeVille.

DeVille sales dropped 11.1 percent in 2002 after a 9.7-percent year-to-year loss in calendar '01. The rival Lincoln Town Car was down a similar amount and likely for the same reason: a dwindling audience for Detroit-traditional luxury sedans.

Sources still expect a fully redesigned DeVille for 2006, but now say it might switch to rear-wheel drive. Earlier, it appeared the replacement would stay with front drive to maximize interior space and winter-weather handling, factors deemed important to DeVille buyers. Now it seems Cadillac is having second thoughts. That's because a rear-drive model could borrow much from the Seville-replacing 2005 STS, which will use a stretched version of the rear-drive Sigma platform that underpins Cadillac's entry-level CTS sedan and upcoming '04 SRX crossover. Then again, GM is devising a new platform for large front-drive cars like the redesigned 2005 Buick LeSabre, so there's no reason for DeVille to go rear drive unless the number-crunchers say otherwise.

Whatever the final answer, the next DeVille should be badged DLS or DTS depending on model. It will definitely get the updated "Gen II" version of Cadillac's respected Northstar V8, plus edgier styling and all sorts of creature comforts.
