To estimate the price of the 2021 Audi Q3 35 TFSI I4 1.4L Turbocharged (Base) with 76000 km mileage, I considered the following data points: 1. A 2021 Audi Q3 35 TFSI with 44000 km sold for 132600 SAR in January 2024. This car had a mid variant and average condition. 2. A 2022 Audi Q3 35 TFSI with 28000 km sold for 117000 SAR in June 2024. This car also had a mid variant and average condition. 3. A 2023 Audi Q3 35 TFSI with 11000 km sold for 170000 SAR in August 2024. This car had a mid variant and good condition. 4. Listed prices for similar cars ranged from 126000 SAR to 187000 SAR, but these are generally higher than actual selling prices. Considering the higher mileage and base variant of the target car, I adjusted the price downwards from the mid variant prices. The average selling price of the 2021 model with lower mileage was 132600 SAR, so I adjusted for higher mileage and base variant to arrive at the final estimate.
