The most relevant data point is the selling price of a 2019 Lexus RX350 3.5L V6 4WD, Platinum (Mid+) variant, with a mileage of 197125 km, sold for AED 111500 in May 2024. The car to be estimated is a 2019 Lexus RX350 V6 3.5L Prestige (Mid) with 150500 km. The Prestige variant is generally considered lower than the Platinum variant, so the estimated price should be slightly lower than AED 111500. Considering the mileage difference and the fact that the car is in average condition, I estimate the price to be around AED 108000.
