Road Map Generous service plans and warranties can keep you covered on the road ahead.

Service plans and warranties are particularly important to business owners who rely on vehicles to conduct their daily business. Checking out what's covered by the manufacturer and the services provided when repairs are needed is crucial when buying new cars and trucks. Every auto manufacturer provides warranty coverage delineated by the number of years and/or miles driven.

However, this year, there is one great exception. To emphasize the quality and reliability of its vehicles, Chrysler has set the industry on its head with a history-making powertrain warranty that covers the life of the vehicle. It applies to most Chrysler, Dodge and Jeep vehicles purchased as far back as July 26, 2007, and it covers the engine, transmission and drive system.
