To estimate the price of the 2023 Toyota FJ Cruiser GXR V6 4.0L GXR (Mid) with 42000 km mileage, I considered several data points. The closest match in terms of variant and mileage is the car sold on 2024-04-21 for AED 150000 with 40000 km, which is the Extreme (Top) variant. The accepted offer for a similar GXR variant with 29000 km was AED 143000 on 2024-01-25. Dealer sales for the GXR RB variant with mileages ranging from 15693 km to 53605 km had prices between AED 108535.65 and AED 142799.15, with most prices clustering around AED 141000 to AED 142800. Given the target car's mileage of 42000 km, which is higher than most dealer-sold cars but lower than the highest mileage, I adjusted the price slightly lower than the top-end dealer prices but higher than the lowest dealer price.
