To estimate the price of the 2017 Toyota Corolla I4 1.6L XLI (Base) with 160837 km mileage, I focused on the selling prices of similar cars. The most relevant data point is a 2017 Corolla XLI (Base) with 265000 km sold for 31500 SAR on 2024-07-28. This car has higher mileage, suggesting a slightly higher value for the target car. Another 2017 Corolla XLI Executive (Base+++) with 155000 km sold for 36000 SAR on 2024-06-18, indicating a higher trim level. A 2018 Corolla XLI (Base) with 184000 km sold for 36000 SAR on 2024-05-05, which is newer but has higher mileage. Considering these, the target car's value is likely between 31500 and 36000 SAR. Given its average condition and mileage, I estimate the price closer to the lower end of this range.
