The car to be estimated is a 2013 Lexus ES250 I4 2.5L Elegant (Base) with 279,000 km mileage. We have listed prices for 2014 models, which are one year newer. The closest match is a 2014 Lexus ES250 I4 2.5L Elegant (Base) with 152,000 km listed for SAR 76,000. Considering the higher mileage of the 2013 model, we expect a significant reduction in price. The 2014 Excellence Plus (Mid) with 324,000 km is listed for SAR 46,500, indicating a lower price for higher mileage. Given the 2013 model's age and mileage, a reasonable estimate would be lower than the 2014 base model with lower mileage. Factoring in the mileage and age, the estimated price is adjusted to reflect these conditions.
