To estimate the price of the 2016 BMW 520 I4 2.0L Twin Power Turbo Standard, I first considered the selling prices of similar cars. A 2016 model with 167,000 km sold for 55,500 SAR in November 2023, and another with 251,000 km sold for 54,500 SAR in December 2023. These cars were in average condition. A 2016 model with 75,800 km in good condition sold for 82,000 SAR in May 2023. A 2015 model in good condition with 209,000 km sold for 48,000 SAR in May 2023. A 2018 model with 126,000 km in average condition sold for 72,000 SAR in May 2024. The target car has 139,589 km and is in good condition, which is better than the average condition of the first two 2016 models. Considering the mileage and condition, the target car should be valued higher than the 55,500 SAR and 54,500 SAR sales. The listed prices for similar cars range from 56,500 SAR to 77,500 SAR, with a car having similar mileage listed for 60,000 SAR. Taking into account the selling prices and the listed prices, I estimate the market price to be slightly above the highest selling price of 55,500 SAR but below the listed prices of 72,500 SAR and 77,500 SAR, considering the car's good condition and mileage.
