To estimate the price of the 2014 Mercedes GL500 V8 4.7L Twin Turbo with 201546 km mileage, I first considered the selling prices of similar cars. A 2015 model with similar specs and 204000 km mileage sold for 66300 SAR in September 2024, and another 2015 model with 108500 km sold for 98449 SAR in October 2024. The 2015 model with 96000 km sold for 135000 SAR in December 2023. Given the target car's older model year and higher mileage, its value should be lower than these. I also looked at listed prices: a 2014 model with 218000 km was listed for 63000 SAR, and a 2013 model with 213000 km was listed for 77000 SAR. Considering these data points, the target car's price should be slightly lower than the 2014 listed price due to its mileage and condition. Therefore, I estimate the market price to be around 62000 SAR.
