BMW 420 offers outstanding driving comfort and its design has received a number of awards. AutoUncle provides access to 1,572 available options in the UK, each one gathered from an online marketplace or dealership website.
A used BMW 420 costs between £8,980 for the cheapest variant and £44,000 for the most expensive model.
The price for the German car is determined by five main factors: year of production, engine capacity and power, fuel economy of the car, how far the car has already travelled and the equipment level of the car.
For instance, a car that is younger with a lower number on the odometer, or more luxurious models with more potent engines will generally cost more than a car from an older model year, with higher mileage and no optional extras.
The most popular equipment variants for the BMW 420 are:
When reviewing the price points of used BMW 420 cars, it is important only comparing the prices of cars with the same engine and trim level. If you don't, you might come to a wrong decision on which car to acquire.
The principal fuel kind for a BMW 420 is diesel.
BMW 420 fuel types compared:
We highly recommend thinking about your driving habits before deciding between the different fuel types. Do you primarily use your car to commute, and is the distance 35 miles or fewer each way?
If your trips are mostly short, electric, plug-in hybrid or petrol may make the most sense. For daily long-distance driving, the electric car is often ideal - especially with a charger 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. Diesel cars can still make sense if you drive very far and don't have access to charging. Consider that in many countries, cities have banned the entry of diesel engines with high emissions.
The BMW 420 comes in various body types, coupe being the most popular. The coupe as a body type prioritises style and sporty driving. Compared to a sedan or an SUV, the chassis tends to be tighter and stronger. This body type is mostly for people without children, who usually travel light. This style is often more expensive than equivalent sedan or hatchback sister models.
Although the BMW 420 is among the most popular cars in its segment it has some competitors.
