On the hunt for a used BMW M850?

Are you considering purchasing a used sports car? Then the BMW M850 is a popular choice. In total, there are 34 used BMW M850s for sale on AutoUncle in the UK, each one collected from an online marketplace or dealership website.

How much does a used BMW M850 cost?

The price of a used BMW M850 ranges from £35,995 for the cheapest model to £78,898 for the latest and most well-equipped model.

There are five main elements that affect the price of a used BMW M850: what year the car is from, engine capacity and power, fuel efficiency of the car, how many miles it has travelled not to mention the vehicle's equipment variant.

For instance, a more recent model with lower mileage, or a luxury edition with a robust engine, usually garners a premium price than, for example, an older model with more kilometres driven or with a lower equipment level.

What equipment levels does the BMW M850 offer?

While calculating the cost of a used BMW M850, it's key to compare vehicles with identical engines and equipment. Otherwise, you might draw an inaccurate conclusion about which car to purchase.

What are the available fuel options for the BMW M850?

The sole fuel type for the BMW M850 is petrol. We currently offer thirty-four cars at an average price of £48,539.

Your driving tendencies should play a significant role in your fuel type selection. Is your driving mainly in the city or on long stretches of open roads and motorways? What's your typical weekly driving distance?

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. 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. If you often drive long distances and can't charge, diesel can still be a viable option. It’s worth noting that diesel engines with high emissions are banned from entering cities in certain countries.

Does the BMW M850 have multiple body styles?

On AutoUncle, the BMW M850 is exclusively offered in the coupe body style. 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.
