To estimate the price of the 2013 Cadillac ATS I4 2.5L Premium Luxury (Mid+), I considered the listed prices of similar cars. The closest match is a 2013 Cadillac ATS I4 2.5L Premium Luxury (Mid+) with the same mileage listed for SAR 32000. Another 2013 model with much higher mileage (314000 km) was listed for SAR 35000 but delisted in 2023. For 2015 models, prices vary significantly based on trim and mileage, with a Premium Luxury (Mid+) variant listed for SAR 67500 with 59000 km. Given the age and mileage of the target car, I adjusted the price downwards from the SAR 32000 listing to account for market depreciation and condition.
