Are you considering getting a pre-owned executive car? The BMW 640 is a solid choice. AutoUncle has 135 used BMW 640 for sale in the UK gathered from numerous dealership websites and online marketplaces.
A used BMW 640 costs between £7,579 for the cheapest variant and £23,000 for the latest and most well-equipped model on AutoUncle.
The German car costs very different determined by mainly five factors: year of production, engine size and performance, fuel consumption, how many miles the car has travelled not to mention the level of equipment in the car.

Fuel types for BMW 640:
Your driving behavior is an important aspect to consider when selecting a fuel type. Are you more often driving in urban areas or on expansive roads and motorways? How many miles do you usually drive each week?
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. 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 640 is only available in the coupe body type in the UK. As a body type, the coupe prioritises style and sporty driving. This body type usually has a tighter and stronger chassis than a sedan or an SUV, and the model is well-suited to people without children and others who travel light. Coupes tend to be more expensive than their sedan or hatchback sister models.
