To estimate the price of the 2021 Toyota FJ Cruiser 4.0L GXR RB Standard (Base) with 57720 km mileage and average condition, I considered several data points. First, I looked at the selling prices of similar cars: a 2021 FJ Cruiser VXR (Mid) with 32000 km sold for 126500 AED and a 2021 FJ Cruiser Extreme (Top) with 42600 km sold for 133000 AED. These cars are in better condition and have lower mileage, so their prices are higher. Next, I considered an offer accepted for a 2021 FJ Cruiser Standard (Base) with 70000 km at 125500 AED, which is closer in condition and variant. Additionally, a dealer sold a 2021 FJ Cruiser 4.0L GXR RB with 32342 km for 131749.15 AED, but this car had lower mileage. Lastly, I reviewed listed prices: a 2021 FJ Cruiser Standard (Base) with 64000 km listed for 135000 AED, and another with 65112 km listed for 148901 AED, but these are higher than actual selling prices. Considering the average condition and mileage of the target car, I adjusted the estimate accordingly.
