I started by looking at the selling prices of similar cars. The most relevant data point is the 2021 Lexus GX460 4.6L V8 Premier (Base) with 33,000 km sold for 183,500 AED in June 2023. The car in question has higher mileage at 47,499 km and is in average condition, so its value should be lower. The 2019 model with 106,700 km sold for 148,000 AED in November 2023, which suggests a depreciation trend. Dealer sales for 2021 models with similar mileage (45,596 km and 66,069 km) were around 161,491.5 AED in October 2023. Considering the car's average condition and higher mileage compared to the 33,000 km car, I estimate the price to be slightly lower than the dealer sales. The listed prices are higher, but they are not reliable indicators of actual selling prices.
