J.D. Power's Vehicle Dependability Study released

When it comes to research about reliable cars, there are two highly respected sources -- Consumer Reports and J.D. Power and Associates.

The latter's 2008 Vehicle Dependability Study shows that the most reliable cars are made by Lexus. They're followed by Mercury, Cadillac, Toyota and Acura.

When it comes to the worst of the worst, Land Rover is in last place -- again. Faring slightly better were Suzuki, Kia, Isuzu and Saab. In fact, Saab was named as the most-improved nameplate this year.

In addition to J.D. Power's tally, you should also check the April issue of Consumer Reports each year -- particularly if you're in the market for a used car.
