To estimate the price of the 2019 Tesla Model S P100D Long Range with 84000 km mileage, I first looked at the selling price of a similar 2018 Tesla Model S 100D Dual Motor Autopilot with 94254 km mileage, which sold for AED 127149 on 2024-06-28. This car is a mid-variant, so the top variant P100D should be priced higher. Next, I reviewed the listed prices of similar cars. The closest match is a 2019 Tesla Model S P100D Long Range with the same mileage listed for AED 189750. Another 2019 Tesla Model S P100D Ludicrous with 51500 km is listed for AED 235000. Considering the higher mileage of the target car, its price should be lower than these listings. Additionally, a 2018 Tesla Model S P100D with 172000 km is listed for AED 145000, and a 2017 Tesla Model S P100D with 183667 km is listed for AED 101500. Given the target car's lower mileage and newer model year, its price should be higher than these older models. Balancing these data points, I estimate the market price to be slightly lower than the highest listed price but higher than the older models with higher mileage.
