To estimate the price of the 2012 Mercedes CLC350 V6 3.5L Standard coupe with 204000 km mileage, I first looked at the new car price for the same model, which is AED 172500. Applying a 10% depreciation per year over 12 years, the estimated value would be around AED 48,000. However, this is a theoretical value. I then considered the classified ad prices for similar cars. The prices range from AED 27,500 to AED 49,000, with most listings around AED 34,000 to AED 38,000. Given the higher mileage and average condition of the target car, I adjusted the estimate towards the lower end of this range.
