To estimate the price of the 2013 Mercedes GL500 4.7L Turbo V8 Top in bad condition with 237600 km mileage, I first looked at the selling prices of similar cars. A 2013 GL500 with 47000 km in good condition sold for AED 75500 on 2023-10-21, and a 2014 GL500 with 125500 km in average condition sold for AED 71000 on 2024-02-10. Given the higher mileage and worse condition of the target car, I adjusted the price downwards. Next, I reviewed listed prices of similar cars. A 2013 GL500 with 230000 km was listed for AED 57500, and another 2013 GL500 with 266100 km was listed for AED 33000. Considering the bad condition of the target car, I estimated a price lower than these listings. Finally, I factored in the depreciation and the overall market trend for similar cars.
