Reasons to Choose a Used BMW 340i

Equipped with a turbocharged inline-six engine, the 340i offers more horsepower than many other models in the 3 Series line.

It even boasts an impressive zero to sixty mph in just under five seconds. Few other BMW 3 Series can compete with the quickness of the 340i.

Of course, the aspect of affordability is another big advantage. The price of a new BMW 3 Series can be steep. But, by choosing a used model, you can experience the luxury and power of a 340i for a fraction of the cost.

When you buy a used car, you avoid the dramatic depreciation that new vehicles experience in their first few years.

Performance and Gas Mileage

Kicking off with the engine and performance, the 2022 BMW 340i is a true standout. Its heart is a 3.0-liter engine that delivers a robust 382 horsepower and 369 lb-ft of torque. Whenever you hit the gas pedal in this ride, you’re sure to feel that instant response and power.

Despite its high performance, the 340i doesn’t compromise on fuel efficiency. When fitted with an automatic gearbox, the 2018 model offers a well-rounded fuel efficiency of 21 mpg in the city and 31 mpg on the highway. It’s this practical efficiency that makes the BMW 340i a great pick for daily commutes and long road trips with family.


Inside, you’ll find high-quality materials and comfortable seating. Specifically, many used BMW 3 Series vehicles come with:

  • Leather upholstery
  • Heated and power-adjustable front seats
  • Dual-zone automatic climate control
  • Sunroof

Ambient lighting illuminates the cabin to enhance your driving experience, especially during night-time drives.

The instrument panel is designed with the driver in mind, featuring an intuitive layout that puts all essential controls within easy reach. Large, clear gauges and a high-resolution infotainment screen provide vital vehicle information at a glance.

Space is a standout feature of the BMW 340i. Front and rear passengers enjoy generous legroom, and the seats give excellent support for long journeys. The trunk has plenty of room for luggage, too.

Equipped with BMW’s iDrive infotainment system, the 340i includes tech features like navigation, Bluetooth, and a Harman Kardon sound system.


Mileage matters, but it’s not everything. While high mileage may indicate longer periods of use, it doesn’t mean that the car has more problems. Some high-mileage cars have been well-maintained and can still be a smart choice.

A used car with documented oil changes, tire rotations, and regular inspections can fare much better than a car with low mileage that hasn’t been serviced as thoroughly.


It’s critical to take a good, hard look at the car’s condition, inside and out. Paint, bodywork, tires, upholstery, and electronics all deserve thorough inspections.

A car with visible wear and tear, or signs of poor upkeep, can be a red flag. An owner who neglects the car’s appearance might also have neglected vital maintenance.

A clean, well-kept car usually indicates that its owner took the time to ensure its mechanical systems were also properly maintained.

VIN Check

A VIN is a special code made up of seventeen characters. Every car has one. It’s like the car’s unique fingerprint.

You can use websites like the National Highway Traffic Safety Administration to check a vehicle’s VIN. Carfax, NICB, and are other services that will help you find out more about the car’s past.

Accident history is one of the big things a VIN check can reveal. Check for any serious mishaps that occurred in a car’s history report. A dent or scratch is fine, but if the car has been totaled in the past or has had major body work done, you should skip it.

Recalls are another key piece of the car’s history that a VIN check can reveal.

Car manufacturers sometimes find out that a part in their automobiles doesn’t work right. When that happens, they’ll recall the cars to replace the part for free. But if the earlier owner didn’t take care of this, it becomes your problem.

BMW Reliability

Yes, the BMW 340i is a reliable vehicle. For instance, the owner of a 2021 M340i xDrive reported no issues after driving ten thousand miles in a single year.

However, like all vehicles, the 340i can have some problems now and then. Proper maintenance and care can enhance the reliability of a pre-owned BMW.

Common Issues

These cars may sometimes experience water pump breakdowns or thermostat failures. These are parts that help your car keep cool while you’re driving. You might need to replace them after several years of use.

Before 2015, some models had problems with the N20 engine’s timing chain. It’s a good idea to check this out if you’re interested in an older model.


Usually, used luxury cars cost more to maintain.

BMW’s maintenance program covers basic needs like oil changes and brake inspections. BMW also offers a comprehensive warranty and roadside assistance.

Alternatively, you can visit BMW San Luis Obispo for regular service. They’ll check your vehicle and make sure everything is in good working order.
