To estimate the price of the 2014 Mercedes GL500 V8 4.7L Bi Turbo Top with 215300 km mileage, I first looked at the selling prices of similar cars. The closest match is a 2014 GL500 with 125500 km sold for 71000 AED in February 2024. Considering the higher mileage of the target car, I adjusted the price downwards. Another 2016 GL500 with 135000 km sold for 72500 AED in May 2024, but it is a newer model, so I adjusted the price further down. The accepted offer for a 2014 GL500 with 167800 km was 75000 AED in November 2023, which also suggests a lower price for higher mileage. The listed prices for similar cars range from 58000 to 70000 AED, with the closest match being listed for 62000 AED. Taking all these data points into account, I estimated the market price accordingly.
