The car to be estimated is a 2020 Mazda 3 1.6L (Mid) sedan with 51,000 km mileage. The most relevant data point is the 2019 Mazda 3 1.6L (Mid) sedan with 94,500 km sold for 38,000 AED on 2024-07-05. This car is one year older and has higher mileage, so the estimated price should be higher. The 2019 Mazda 3 1.6L (Base) sedans sold for around 31,500 to 32,000 AED in July 2024, but these are base variants. The 2020 Mazda 3 2.0L (Top) sold for 64,000 AED in February 2024, but this is a higher variant. Considering the 2020 model year, mid variant, and lower mileage, the estimated price should be slightly higher than the 2019 mid variant but lower than the 2.0L top variant. Therefore, the estimated price is around 42,000 AED.
