To estimate the price of the 2016 Mercedes GL500 4MATIC Standard with 197000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2016 GL500 with 152000 km sold for AED 80000 on 2023-11-07, a 2016 GL500 with 95750 km sold for AED 100000 on 2023-11-04, a 2014 GL500 with 125500 km sold for AED 71000 on 2024-02-10, a 2016 GL500 with 135000 km sold for AED 72500 on 2024-05-09, and a 2014 GL500 with 215300 km sold for AED 52099 on 2024-09-10. The average selling price of these cars is around AED 78520. Considering the higher mileage of the target car (197000 km), I adjusted the price downwards. I also noted that a similar car with 152000 km had an accepted offer of AED 80000 on 2023-11-01. Listed prices for similar cars ranged from AED 80000 to AED 95000, but these are generally higher than actual selling prices. Taking all these factors into account, I estimated the market price accordingly.
