To estimate the price of the 2018 Toyota Hiace 2.7L GL Standard with 305567 km mileage, I considered the listed prices of similar cars. The closest match is a 2018 Toyota Hiace 2.7L GL Standard with the same mileage listed for AED 92990. However, listed prices are generally higher than actual selling prices. Other 2018 models with lower mileage are listed for AED 64990. Considering the higher mileage and average condition of the target car, I adjusted the price downwards. The 2020 models with similar mileage are listed between AED 69990 and AED 84990, but they are newer and have a larger engine. Therefore, the estimated price should be lower than these. Taking all these factors into account, I arrived at a final estimate.
