To estimate the price of the 2018 Cadillac XT5 V6 3.6L Premium Luxury, I started by looking at the new car prices for the 2025 model. The 2025 Cadillac XT5 Premium Luxury (Mid) SUV is priced at SAR 248,000. Assuming a 10% annual depreciation, the car would depreciate approximately 60% over 6 years (2018 to 2024). This results in a depreciation of SAR 148,800, bringing the estimated value to SAR 99,200. Given the car's good condition and Canadian specs, I adjusted the price slightly upwards to account for these factors.
