To estimate the price of the 2012 BMW 535 I6 3.0L Twin Power Turbo, I first considered the selling prices of similar cars. A 2012 model with the same engine and variant but higher mileage (278,000 km) sold for 41,000 SAR in March 2024. This car is in average condition, similar to the target car. A 2013 model with a different engine (I4 2.0L) and lower mileage (117,000 km) sold for 62,000 SAR in October 2023, but it was in good condition. The listed prices show a 2012 model with the same engine and higher mileage listed for 45,000 SAR, and a 2011 model with even higher mileage listed for 26,800 SAR. Considering the target car's mileage (172,000 km) and average condition, its value should be slightly higher than the 2012 model sold for 41,000 SAR but lower than the 2013 model sold for 62,000 SAR. Taking into account the depreciation and condition, I estimate the market price to be around 44,000 SAR.
