To estimate the price of the 2023 Toyota Supra 3.0L GR GR (Top) with 20357 km mileage, I first looked at the selling prices of similar cars. A 2023 Toyota Supra 3.0L GR with 14320 km was sold for AED 175865 on 2024-08-11, and another with 2900 km was sold for AED 177565 on 2024-07-30. These prices are for cars with lower mileage than the target car. Next, I considered the listed prices of similar cars. The closest match is a 2023 Toyota Supra 3.0L GR with 20357 km listed for AED 204488. Other listings include cars with slightly different mileages, ranging from AED 194750 to AED 208900. Given the average condition of the target car and its mileage, I adjusted the estimate slightly lower than the average of the listed prices but higher than the selling prices due to the higher mileage and average condition.
