To estimate the price of the 2015 Cadillac CTS I4 2.0L Turbo Charged 6.2 CTS V (Top) with 240000 km mileage, I first looked at the selling price of a 2013 Cadillac CTS V6 3.0L with 157651 km mileage, which sold for SAR 23250 in March 2024. Given that the car in question is a higher trim (CTS V) and newer by 2 years, I adjusted the price upwards. Next, I considered the listed prices: a 2015 Cadillac CTS I4 2.0L Turbocharged with 152000 km is listed for SAR 48000, and another 2015 Cadillac CTS I4 2.0L Turbocharged with 122500 km is listed for SAR 63000. Given the higher mileage and average condition of the car in question, I adjusted the price downwards from these listings. The final estimate balances these factors.
