You might have noticed that BMW 6 Series cars are surprisingly affordable in the used car market. One of the main reasons for their relatively low price is due to depreciation.

Just like many luxury vehicles, the costs for maintenance and repairs increase substantially once these cars have been driven for more than 50,000-60,000 miles.

Another factor contributing to their lower prices is the oversaturated market. With an abundance of BMWs available, buyers have plenty of options and sellers are more inclined to reduce prices to attract buyers.

In addition to few BMW 6 Series problems and common issues, the 6-Series also stopped production in 2019, which has an impact on the current supply and, therefore, the prices.

Why Are BMW 6 Series So Cheap

Reasons for Lower Prices in the BMW 6 Series


One of the main reasons you might find a BMW 6 Series at a lower price is depreciation. Like many luxury cars, BMW vehicles tend to depreciate faster than other brands.

This means that even a few years after purchase, the value of a 6 Series can drop significantly, making it more affordable for buyers in the used market.

For example, the average used BMW 3-series sedan sells for around $20,000, similar to the average price of a used Audi A4 or Lexus IS.

Market Oversaturation

Another factor contributing to the lower prices of the BMW 6 Series is market oversaturation. There is a high supply of BMWs on the market, with many people trading in their older models for newer ones.

This increased availability of used BMW 6 Series models makes them more competitively priced and easier to find at a lower price point.


The BMW 6 Series was discontinued in 2018. As a result, the demand for this specific series has likely decreased over time, leading to lower prices on the used market.

Furthermore, rumor has it that BMW might merge the 4 and 8 Series into a new 6 Series range in 2026, which could cause the prices of current 6 Series models to decline further.

Aging Models

Lastly, the age of the BMW 6 Series models can also contribute to their lower prices. As the vehicles get older, they may require more maintenance and repairs, making them less appealing to prospective buyers.

This leads to a reduced demand and ultimately lowers the price for older BMW 6 Series cars. For example, earlier 2004-2006 models can sell for around $10,000, depending on the mileage, age, and condition.

In summary, if you’re in the market for a reasonably priced luxury vehicle, the BMW 6 Series offers an attractive option due to factors such as depreciation, market oversaturation, discontinuation, and aging models.
