Trims Explained

When talking about cars, “trims” is a way of differentiating between different versions of the same model. Typically, most start with a no-frills, or “base” trim, and as features are added, or a different engine, drivetrain (gas vs. hybrid, for example) or transmission are included, trim names change and prices go up. It’s important to carefully check the trims of the car you’re interested in to make sure that you’re getting the features you want, or that you’re not overpaying for features you don’t want.

Warranty Coverage





Roadside Assistance Coverage


What you should get in your warranty can be confusing. Make sure you are informed.

Learn More About Warranties

Warranties Explained


Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.


Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

Roadside Assistance

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

Free Scheduled Maintenance

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.
