To estimate the price of the 2015 Mercedes GL500 V8 4.7L 4MATIC Top in bad condition with 201000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars. A 2013 model in good condition with 47000 km sold for 75500 AED, a 2016 model in average condition with 95750 km sold for 100000 AED, another 2016 model with 152000 km sold for 80000 AED, a 2014 model in average condition with 125500 km sold for 71000 AED, and a 2016 model in average condition with 135000 km sold for 72500 AED. Given the bad condition and high mileage of the target car, I adjusted the price downwards. I also considered offers accepted by sellers for 2015 models with similar mileage, which were around 68000 AED. Lastly, I looked at listed prices, where a 2015 model with 181000 km was listed for 63000 AED and another with 161000 km was listed for 104000 AED. Taking into account the bad condition and higher mileage, I estimated the market price accordingly.
