To estimate the price of the 2021 Lexus LX570 5.7L Signature Premier (Base) with 40427 km mileage, I first considered the selling prices of similar cars. A similar car with higher mileage (76100 km) and a higher trim (Signature Top) sold for AED 337500 on 2024-10-01. Dealer sales of similar cars with varying mileages and trims ranged from AED 327241.5 to AED 365491.5, with the most recent sales on 2024-10-17 being AED 356787.5 and AED 356995.75 for cars with mileages of 34402 km and 50218 km, respectively. These cars are closer in mileage and condition to the target car. Listed prices for the Premier (Base) variant, which is the same as the target car, range from AED 384990 to AED 419995, but these are typically higher than actual selling prices. Considering the target car's average condition and lower mileage compared to the sold cars, I estimate its market price to be slightly lower than the recent dealer sales, around AED 355000.
