To estimate the price of the 2013 Mercedes GL500 5.5L V8 Standard, I first considered the selling prices of similar cars. The closest match is the 2013 GL500 4.7L V8 TC with 47,000 km sold for 75,500 AED, but it has much lower mileage and is in good condition. A 2014 GL500 4.7L V8 with 125,500 km sold for 71,000 AED, but it is a top variant. The 2011 GL500 5.5L V8 Standard with 115,300 km sold for around 41,000 AED, but it is older. The 2014 GL500 with 215,300 km sold for 52,099 AED, but it is a top variant. For listed prices, a 2013 GL500 5.0L V8 Standard with 183,000 km was listed for 49,000 AED, and a 4.7L V8 with 155,600 km was listed for 53,000 AED. Considering the target car's higher mileage and average condition, I estimate its market price to be slightly lower than these listed prices.
