To estimate the price of the 2017 Audi A4 1.4L 30 TFSI (Base) with 102500 km mileage, I first looked at the selling prices of similar cars. A 2015 Audi A4 2.0 I4 45 TFSI Quattro (Top) with 119300 km sold for AED 41000 in February 2024, and a 2015 Audi A4 2.0L Turbo I4 30 TFSI (Base) with 45300 km sold for AED 36000 in June 2024. These cars are older and have different variants, but they provide a baseline. Next, I considered the listed prices of similar 2017 Audi A4 1.4L 30 TFSI (Base) models: AED 52000, AED 55000, and AED 51500. These prices are higher than the selling prices, reflecting typical listing inflation. Given the car's average condition and higher mileage, I adjusted the estimate downward from the listed prices but higher than the older sold prices. Factoring in the car's age, condition, and market trends, I arrived at a reasonable estimate.
