To estimate the price of the 2019 Mercedes GLE43 AMG V6 3.0L Biturbo Standard with 73500 km mileage, I analyzed the listed prices of similar cars. The closest matches are the 2019 models with similar mileage and specs. The listed prices for 2019 models range from AED 220,000 to AED 261,000. The most relevant listings are: AED 239,999 (67000 km), AED 220,000 (57000 km), and AED 235,000 (74000 km). Considering the mileage and condition of the target car, I adjusted the price slightly lower than the highest listed price but higher than the lowest, as the target car's mileage is between these examples.
