The car to be estimated is a 2021 Toyota Prado VX.L V6 4.0L VX1 (Top) with 86574 km mileage. The most relevant selling price is for a 2019 Toyota Prado V6 4.0L TXL1 (Mid) with 94300 km sold for 140000 SAR in March 2024. This car is a lower trim than the VX1 but provides a baseline for V6 models. A 2020 Prado TX.L V6 4.0L TXL1 (Base+) with 95000 km sold for 140000 SAR in August 2023, indicating stability in V6 prices. Listed prices for similar V6 models like a 2021 Prado V6 TXL1 (Mid) with 48000 km at 165000 SAR and a 2023 Prado V6 VX1 (Top) with 14000 km at 214500 SAR suggest higher values for newer and lower mileage cars. Considering the target car's higher trim and average condition, an estimate slightly above the 2019 V6 TXL1 selling price is reasonable.
