I analyzed the selling prices of similar cars first. A 2023 Lexus GX460 4.6L V8 Premier with 13900 km sold for AED 213500 on 2024-05-30, and another with 26500 km sold for AED 207000 on 2024-07-07. These cars are in good condition and have lower mileage than the car in question, which has 39977 km and is in average condition. I also considered dealer sales: a Premier with 30135 km sold for AED 186991.5 on 2024-05-11, and another with 28140 km sold for AED 197195.75 on 2024-07-02. Given the higher mileage and average condition of the car in question, I estimate its price to be slightly lower than these dealer sales, around AED 185000.
