To estimate the price of the 2015 Mercedes GL500 4 Matic V8 4.7L Top, I first considered the selling prices of similar cars. The 2014 GL500 Top variant with 215300 km sold for AED 52099 and another 2014 Top variant with 144600 km sold for AED 51000. A 2016 Top variant with 135000 km sold for AED 72500. These prices suggest a range for Top variants. The 2015 model's mileage is 210000 km, which is higher than the 2014 models but lower than the 2014 model with 215300 km. The accepted offers for 2015 Standard variants were AED 68000, but these have higher mileage. The listed prices for 2015 Top variants were AED 63000 and AED 97500, but these are not actual selling prices. Considering the selling prices, accepted offers, and listed prices, I estimate the market price for the 2015 GL500 Top variant with 210000 km to be slightly above the 2014 Top variant with 215300 km, around AED 55000.
