On the hunt for a used BMW 640?

Are you thinking of buying a used executive car? Then the BMW 640 is a great option. At AutoUncle, we have assembled a collection of 108 used BMW 640 cars, each one gathered from an online marketplace or dealership website.

How much does a used BMW 640 go for?

A used BMW 640 costs between £8,495 for the cheapest variant and £20,995 for the most expensive model.

The used car price for a BMW 640 varies according to five primary factors: what year the car is from, engine size and performance, the car's fuel consumption, car mileage along with trim level.

As an example, a newer model with fewer miles covered, or a high-end version boasting a potent engine, often fetches a top-tier price than, for example, an older model with more kilometres driven or with a lower equipment level.

What trim levels is the BMW 640 available in?

While evaluating the cost of a pre-owned BMW 640, it's crucial to examine vehicles that have the same engines and features. Otherwise, you might draw an inaccurate conclusion about which car to buy.

In which fuel variants is the BMW 640 offered?

Diesel is the foremost fuel option for the BMW 640.

BMW 640 is available with the following fuel types:

  • BMW 640 diesel: 99 cars currently available with an average price of £13,273
  • BMW 640 petrol: 9 cars currently available with an average price of £17,364

Factor in your driving habits when making a decision about fuel types. In an average week, how much distance do you drive? Are you more inclined to take short drives or to go on longer journeys?

If you primarily drive short distances, electric, plug-in hybrid or petrol is typically a good fit. For longer commutes, a newer electric car is a good alternative - especially with access to charging. If you have a daily commute over longer distances, a modern electric car can be a great choice - especially if you have access to charging at home or at work. Diesel cars may still be relevant in some cases with very long journeys and lack of charging options. Note that diesel engines with significant emissions have faced entry bans in cities across numerous countries.

In which body styles can you buy the BMW 640?

On AutoUncle, the BMW 640 is exclusively offered in the coupe body style. 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.
