To estimate the price of the 2019 Cadillac CT5 I4 2.0L Turbocharged Premium Luxury (Mid), I first considered the selling price of a 2021 Cadillac CT5 I4 2.0L Turbocharged Sport (Top) variant, which sold for SAR 150,000 in September 2023. This car is newer and a higher trim than the target car. Next, I looked at the listed prices of similar cars: a 2020 Cadillac CT5 Premium Luxury (Mid) with 69,486 km listed for SAR 128,000, and a 2020 V-Series (Top+) with 61,700 km listed for SAR 133,000. The target car is a 2019 model with higher mileage (177,760 km), which suggests a lower price than these 2020 models. Considering the depreciation and higher mileage, I estimate the market price of the 2019 model to be significantly lower than the 2020 listed prices.
