To estimate the price of the 2012 Mercedes C200 I4 1.8L Exclusive (Top) with 185000 km mileage and average condition, I first looked at the selling prices of similar cars. The 2013 Mercedes C200 1.8L TC I4 with 215200 km sold for AED 26000 on 2023-11-01, and another 2013 Mercedes C200 1.8L I4 with 225980 km sold for AED 24000 on 2024-05-09. These cars are of a similar model year but have higher mileage and are of the standard variant, which is typically less expensive than the top variant. Next, I reviewed the listed prices of similar cars. A 2012 Mercedes C200 2.0L TC Avantgarde Kit with 200000 km was listed for AED 25500 and delisted on 2024-02-08. This car is also of a similar model year and mileage but is a different variant. Considering the selling prices and the listed prices, I adjusted for the top variant and the slightly lower mileage of the target car. The selling prices suggest a range of AED 24000 to AED 26000, and the listed prices suggest a slightly higher range. Therefore, I estimated the market price accordingly.
