I started by looking at the selling price of a similar car sold by a dealer on 2024-08-16. The car was a 2015 Mercedes S600 with a mileage of 147000 km and it sold for AED 155550. Given that the car to be estimated has a lower mileage of 128600 km, it should be valued slightly higher. Next, I considered the listed prices of similar cars. The closest match is a 2015 Mercedes S600 V12 6.0L with the same mileage of 128600 km listed for AED 140000. Another similar car with higher mileage (147000 km) is listed for AED 183000. The listed prices are generally higher than the actual selling prices. Considering the selling price and the listed prices, I adjusted the estimate to reflect a realistic market value.
