I started by examining the selling prices of similar cars. The 2015 Lexus LS460 L V8 4.6L with 144103 km sold for 125000 SAR in July 2024. This car is similar in year and engine but has lower mileage than the target car. The 2013 Lexus LS460 V8 5.0L with 159000 km sold for 91800 SAR in September 2024. This car is older and has a different engine size. The target car is a 2015 model with 233500 km, which is higher mileage than the 2015 sold car. Considering the mileage difference, the target car's value should be lower than 125000 SAR. Next, I looked at listed prices. A 2015 Lexus LS460 L V8 4.6L with 176500 km was listed for 108500 SAR, and a 2014 model with 340000 km was listed for 72500 SAR. The target car's mileage is between these two, suggesting a price between these values. Considering the selling prices and listed prices, I estimate the market price of the target car to be slightly lower than the 2015 sold car due to higher mileage, around 105000 SAR.
