I started by looking at the selling prices of similar cars. The most relevant data points are: 2016 Toyota Yaris I4 1.3L, sedan, Mileage: 129500, Variant: STD (M/T) (Base+), sold for 21300 SAR on 2023-04-10; 2016 Toyota Yaris I4 1.3L, sedan, Mileage: 139000, Variant: STD (M/T) (Base+), sold for 28000 SAR on 2024-09-12; and 2015 Toyota Yaris I4 1.3L, sedan, Mileage: 224929, Variant: STD (M/T) (Base+), sold for 24500 SAR on 2024-07-24. Considering the mileage and condition of the target car (202000 km, average condition), I adjusted the price downwards from the higher end of the range. The listed price of a similar car was 27500 SAR, but this is typically higher than the actual selling price. Therefore, I estimated the market price by averaging the relevant selling prices and adjusting for the higher mileage and average condition.
