Our Take

from the Cars.com expert editorial team

What it is: BMW's compact 3 Series is the luxury automaker's bread-and-butter model. It's available as a sedan, wagon or Gran Turismo hatchback and as an M3 performance sedan.

Numerous drivetrains are offered, including turbocharged gas four-cylinder engines (320i and 330i models); a turbo-diesel four-cylinder (328d); a turbo gas six-cylinder (340i); and a plug-in hybrid (330e).

The five-seat 3 Series comes with rear- or all-wheel drive (designated xDrive) and competes with the Audi A4, Cadillac ATS and Mercedes-Benz C-Class.

New for 2018

LED headlights are now standard, and BMW’s iDrive 6.0 multimedia system with a touchscreen is available. An available Shadow Sport Edition Package includes 18-inch black-accented wheels, a gloss-black twin-kidney grille, smoked taillights and a leather-wrapped sport steering wheel.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

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.

What is a Powertrain warranty?

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.

What is included in 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).

What other services could be included in a warranty?

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.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
