I started by looking at the selling prices of similar cars. The 2012 Mercedes E300 3.0L V6 with average condition and mileage of 156800 km sold for AED 36500 on 2023-10-01. Another 2012 model with 133000 km sold for AED 30000 and AED 29500 on 2023-10-22. A 2013 model with 155100 km sold for AED 44500 on 2024-05-18. Given the target car is a 2014 model with higher mileage (228000 km), I adjusted the price downwards. The accepted offer for a 2014 model with 180682 km was AED 39000 on 2024-07-11. Listed prices for similar 2014 models ranged from AED 40000 to AED 43000, but these are generally higher than actual selling prices. Considering the higher mileage and average condition, I estimated the market price accordingly.
