To estimate the price of the 2019 Lexus RX350 3.5L Premier Elegant (Base) with 64845 km mileage, I first considered the selling prices of similar cars. A 2019 RX350 V6 4WD with higher mileage (197125 km) sold for AED 111500, but it was a Platinum variant, which is typically more expensive. Dealer sales provide more relevant data: a similar RX350 with 77710 km sold for AED 152995.75, and another with 84760 km sold for AED 135991.5. A car with lower mileage (56765 km) sold for AED 127491.5. These prices suggest a range between AED 127491.5 and AED 152995.75 for cars in average condition. The listed prices are higher, with a similar variant listed for AED 149990 and AED 159990, but these are not actual selling prices. Considering the car's mileage and condition, I estimate the market price to be slightly lower than the dealer sales, around AED 130000.
