The car to be estimated is a 2018 Lexus NX300 I4 2.0L Excellence (Mid) with 103,000 km mileage. We have listed prices for similar cars but no actual selling prices or offers accepted. The closest match is a 2019 Lexus NX300 Excellence (Mid) with 108,000 km listed for SAR 130,000. Considering the 2018 model is a year older, we apply a depreciation of about 10% per year, reducing the price by approximately SAR 13,000. This gives an estimated price of SAR 117,000. Another 2018 model, a Sport (Top) variant with much higher mileage (238,439 km), is listed for SAR 108,000. Given the lower mileage of the car in question, it should be valued higher than SAR 108,000. Balancing these factors, the estimated market price is around SAR 115,000.
