To estimate the price of the 2018 Renault Koleos I4 2.5L LE (Top) with 149000 km mileage, I first looked at the selling prices of similar cars. The closest match is a 2018 Renault Koleos LE (Top) with 43000 km sold for 61500 SAR and 62000 SAR in early 2024. Given the higher mileage of the target car, I adjusted the price downwards. Another 2018 Koleos LE (Mid) with 118000 km sold for 52000 SAR in late 2023, which also supports a lower price for higher mileage. The listed prices of similar cars with higher mileage (149000 km and 189000 km) are 57000 SAR and 52000 SAR respectively. Considering these data points, I estimated the market price by factoring in the higher mileage and the condition of the car.
