To estimate the price of the 2023 Audi A3 35 TFSI, I first considered the new car price for the 2025 Audi A3 Sedan 35 TFSI Advanced, which is SAR 176820. Assuming a 15% annual depreciation, the 2023 model would have depreciated for one year, resulting in an estimated value of SAR 150297. Next, I examined the listed prices of similar cars. The 2023 Audi A3 35 TFSI S-Line with 1000 km is listed for SAR 150500, and the 2022 Audi A3 I4 1.4L with 18000 km is listed for SAR 138500. These listings suggest a price range for similar models. Considering the target car's mileage of 13000 km and its base trim, I adjusted the estimate slightly lower than the S-Line variant but higher than the older 2022 model, leading to a final estimate.
