To estimate the price of the 2021 Toyota Corolla I3 1.5L XLI (Base), I first considered the selling prices of similar cars. A 2022 model with similar specs and mileage sold for 53000 SAR on 6 Nov 2024. A 2020 model with a larger engine (1.6L) and higher mileage sold for 51000 SAR on 1 Oct 2024. These provide a range for the 2021 model. The listed prices for 2021 models with similar mileage range from 53500 to 62000 SAR, but these are typically higher than actual selling prices. Considering the 2021 model's mileage and condition, I estimate its market price to be slightly lower than the 2022 model's selling price, around 52000 SAR.
