I started by examining the selling prices of similar cars. A 2016 Impala LT (Base) with 214,000 km in good condition sold for 42,000 SAR in October 2023. Another 2016 Impala LT (Base) with 153,000 km in good condition sold for 42,500 SAR in February 2024. A 2014 Impala LT (Base) with 232,000 km in average condition sold for 23,500 SAR in January 2024. The car in question has 238,423 km and is in average condition, which is closer to the 2014 model's condition and mileage. The 2015 Impala LT (Mid) with 182,000 km in average condition sold for 45,500 SAR in September 2024, but it is a different variant. The listed prices for similar 2016 Impalas range from 40,000 to 48,000 SAR, but these are higher than actual selling prices. Considering the car's higher mileage and average condition, I estimate the price to be slightly lower than the 2016 models in good condition, around 38,000 SAR.
