To estimate the price of the 2020 Lexus IS300 3.5L V6 Platinum (Top) with 31820 miles, I considered several data points. First, a 2019 Lexus IS300 2.0L i4 TC Platinum (Top) with 72600 miles sold for AED 64000 on 2024-04-23. Given the higher mileage and older model year, this car's lower price is expected. Next, a 2020 Lexus IS300 2.0L I4 Premier (Base) with 64750 miles had an offer accepted for AED 90500 on 2024-03-22. This car has a lower trim and higher mileage, suggesting our target car should be valued higher. Additionally, a similar 2020 Lexus IS300 3.5L V6 Platinum (Top) with the same mileage is listed for AED 83000, which provides a close benchmark. Considering these points, the estimated market price for the target car is derived by balancing these values, giving more weight to the actual selling price and accepted offers.
