Interested in finding a great deal on the popular BMW 120?

Are you interested in purchasing a used medium sized family car? Then the BMW 120 is a popular choice. AutoUncle has 1,163 attractive options ready for you in the UK compiled from different dealership websites and online marketplaces.

What is the cost of a pre-owned BMW 120?

A used BMW 120 costs between £6,495 for the cheapest variant and £34,925 for the most expensive model. A pre-owned BMW 120 can cost different based on primarily five factors: year, engine capacity and performance, fuel economy of the car, how far the car has travelled not to mention equipment. For instance, a car that is younger with a lower number on the odometer, or more luxurious models with more potent engines will typically cost more than a used model with many kilometres on the odometer and in a simple equipment variant.

How many trim levels are available for the BMW 120?

As you considers the cost of a used BMW 120, it's fundamental to examine vehicles that have the same engines and features. If not, you might draw an inaccurate conclusion about which car to purchase.

What fuel configurations can I choose from for the BMW 120?

The number one fuel selection for the BMW 120 is petrol. Types of fuel for BMW 120: BMW 120 petrol : 809 cars currently available with an average price of £28,349 BMW 120 diesel : 202 cars currently available with an average price of £12,287 BMW 120 plug-in hybrid : Currently there is 152 cars available on AutoUncle with an average price of £28,950 Your driving tendencies should play a significant role in your fuel type selection. On average, how many miles do you travel in a week? Do you frequently make short journeys or are your trips generally long? Electric, plug-in hybrid and petrol work well for short trips. If you drive long distances on a daily basis, an electric car is good - especially if you can charge at home or at work. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. Despite the rise of electric cars, diesel can still be useful for long journeys and lack of charging options. Keep in mind that certain countries have bans on high-emission diesel engines entering their cities.

What body types is the BMW 120 available in?

The BMW 120 is only available in the hatchback body type in the UK. Hatchbacks are quite compact and offer a great driving experience as well as ample space. Their fuel efficiency makes them popular with people living in cities, and another key selling point is that they’re easy to park.
