To estimate the price of the 2021 Honda Odyssey V6 3.5L EXL (Mid) with 120000 km mileage, I considered the listed prices of similar cars. The 2020 Honda Odyssey I4 2.4L Touring (Top) with 110000 km is listed for SAR 97500. The 2019 Honda Odyssey V6 3.5L EXL (Mid) with 134000 km is listed for SAR 106000. The 2023 Honda Odyssey V6 3.6L Touring (Top) with 5100 km is listed for SAR 196000. Given that the 2021 model is newer than the 2019 model but has higher mileage, I adjusted the price downwards from the 2019 model's listing. Considering the depreciation and the condition of the car, I estimated the price accordingly.
