To estimate the price of the 2020 Chevrolet Malibu I4 1.5L Turbo LS (Base) with 87500 km mileage, I first considered the selling prices of similar cars. A 2018 Malibu with a 2.5L engine and similar trim sold for 44500 SAR recently, but it had higher mileage and was older. A 2022 Malibu with a 2.0L engine sold for 80500 SAR, but it was a higher trim and newer. The listed prices for 2020 models with similar specs and higher mileage range from 39000 to 52500 SAR. A 2020 model with 129000 km was listed for 45000 SAR, and another with 170500 km was listed for 49000 SAR. Considering the lower mileage of the target car and its average condition, I estimate the market price to be slightly higher than the lower end of these listings, but lower than the higher mileage 2020 models.
