I started by looking at the selling price of a similar car: a 2011 Mercedes C300 3.0L V6 with 109400 miles, which sold for AED 20500 in March 2024. The car to be estimated is a 2012 model with 144000 miles, which is slightly newer but has higher mileage. The listed price for a 2012 model with 130557 miles is AED 18000, and a 2014 model with 142000 miles is listed for AED 25000. Considering the 2012 model's higher mileage and average condition, I adjusted the price slightly lower than the 2011 sold price and the 2012 listed price, taking into account the depreciation and market conditions.
