To estimate the price of the 2014 Mazda 6 I4 2.0L S (Base) with 169100 km mileage, I primarily considered the actual selling prices of similar cars. The closest match is a 2014 Mazda 6 I4 2.0L S (Base) with 264000 km sold for 19500 SAR on 2024-01-21. Given the lower mileage of the target car, it should be valued higher. Another reference is a 2012 Mazda 6 I4 2.0L S (Base) with 284000 km sold for 13000 SAR on 2024-03-14, which also supports a higher value for the target car. The listed price of a similar car with the same mileage is 32000 SAR, but listed prices are generally higher than selling prices. Considering these factors, I estimate the market price to be slightly higher than the 19500 SAR but lower than the listed price.
