The most relevant data point is the selling price of a 2013 Cadillac CTS V6 3.0L with the same variant (3.6L Premium Luxury) and in good condition, which sold for SAR 23,250 in March 2024. The car to be estimated is a 2012 model with higher mileage (248,000 km) and in average condition. Considering the depreciation and condition difference, the estimated price should be lower. The listed prices for 2012 models with different variants and conditions range from SAR 22,000 to SAR 32,500, but these are not actual selling prices. Given the higher mileage and average condition, the estimated price should be closer to the lower end of the range.
