To estimate the price of the 2015 Chevrolet Impala V6 3.6L LTZ (Top) with 344,000 km mileage, I first considered the selling prices of similar cars. A 2016 LTZ with 180,000 km sold for 57,500 SAR in June 2024, and a 2017 LTZ with 103,843 km sold for 60,000 SAR in October 2024. A 2015 LT (Mid) with 182,000 km sold for 45,500 SAR in September 2024. The target car has higher mileage and is in average condition, so its value should be lower. I also looked at listed prices: a 2015 LTZ with 291,095 km is listed for 45,000 SAR, and another with 198,500 km for 56,500 SAR. Considering the high mileage and average condition, I estimate the market price to be lower than these listings, around 35,000 SAR.
