To estimate the price of the 2020 Changan Eado Turbo Charged GDi I4 1.6L Smart (Mid), I first considered the selling prices of similar cars. The 2021 Changan Eado I4 1.6L with 146,000 km in good condition sold for 32,500 SAR in May 2024. The 2018 model with 177,000 km in average condition sold for 21,700 SAR in April 2024. These provide a range for similar models. The 2020 model is newer than the 2018 but older than the 2021, and it has a similar mileage to the 2021 model. I also looked at listed prices: a 2021 Changan Eado Turbocharged I4 1.6L Smart (Mid) with 134,613 km was listed for 32,000 SAR in September 2024. Considering the 2020 model's average condition and mileage, I estimated its price slightly lower than the 2021 model's selling price but higher than the 2018 model's selling price, taking into account depreciation and market trends.
