Consumer Reports' annual auto issue is out and Clark is giddy with excitement. The April '08 issue definitively says that extended warranties aren't worth the investment. Clark has historically been neutral on extended warranties for vehicles, but now he'll have to revise his opinion. Only 20% of people ever recoup the cost of the warranty vs. the cost of repairs over the lifetime of a vehicle. If you're buying a Mercedes, you'll have the best chance (about 40%) in that regard. Other vehicles where a warranty may be a smart move include Pontiacs, Jeeps, Chryslers, Buicks and Dodges.

In other news, there's a new champ when it comes to reliable small cars: Hyundai Elantra. Other top picks included the Honda Accord (family sedan); Toyota Prius (hybrid); Toyota Sienna (minivan); and Hyundai Santa Fe (SUV). American cars are getting more reliable, but they're not quite on par with the Japanese vehicles yet.

When it comes to the best used cars, they're all Japanese: Toyota's Prius, Highlander, RAV 4 (4 cylinder), Corrolla and Honda's Accord (4 cylinder). A new category this year was vehicles that are unloved, but good to own. This category was dominated by Korean vehicles such as the Kia Rondo and the MAZDA5.
