To estimate the price of the 2017 Cadillac CT6 V6 3.6L 3.0T (Top) with 149200 km mileage, I first considered the new car price for the 2025 model, which is AED 292500. Applying a 10% annual depreciation over 7 years, the estimated value is approximately AED 142000. Next, I reviewed the listed prices of similar 2017 Cadillac CT6 3.0T (Top) models. The closest match with 119318 km is listed at AED 99120. Considering the higher mileage of the target car, I adjusted the price downward. Classified listings for similar mileage cars range from AED 58000 to AED 85000, with an average around AED 72000. Given the condition and mileage, I estimate the market price to be slightly above the average classified price but below the listed price for lower mileage cars.
