To estimate the price of the 2018 Volkswagen Passat I5 2.5L Highline with 65000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars. The closest match is the 2016 Passat I5 2.5L Highline with 141000 km sold for 32500 SAR and 34500 SAR in February 2024. Given the lower mileage of the target car, it should be valued higher. The 2018 Passat I4 2.5L Trendline with 156000 km sold for 41000 SAR in May 2024, indicating a higher value for newer models. The listed prices for similar 2018 Passat Highline models are 68500 SAR and 68000 SAR, but these are typically higher than actual selling prices. Considering the depreciation and the condition, I adjusted the price downwards from the listed prices but higher than the older models with higher mileage.
