To estimate the price of the 2023 Genesis GV80 V6 3.5L Twin Turbo Royal (Top) with 21100 km mileage, I first considered the selling price of a similar car: a 2023 Genesis GV80 3.5T Royal (AWD) with 19000 km sold for AED 221000 on 2024-06-26. This is a strong indicator of the market value. Next, I looked at listed prices of similar cars. The closest match is a 2023 Genesis GV80 3.5 twin turbo V6 Royal (Top) with 23000 km listed for AED 275500, and another with 16000 km listed for AED 269750. These prices are higher than the selling price, indicating that listed prices are generally above actual selling prices. Considering the average condition of the car in question, I adjusted the estimate slightly lower than the selling price of the dealer-sold car to account for the condition and slightly higher mileage.
