To estimate the price of the 2014 Audi A3 Turbo I4 1.8L 40 TFSI S-Line (Top) with 174000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars. A 2015 Audi A3 1.8L I4 with 85512 km sold for AED 40000 in September 2023. A 2016 Audi A3 1.8L TC i4 with 86000 km sold for AED 46500 in February 2024. These cars have lower mileage and are newer, so their prices are higher. The 2016 Audi A3 2.0 Turbo V4 with 165000 km sold for AED 31000 in November 2023, which is closer in mileage but a different variant. The listed prices of similar cars also provide insight. A 2014 Audi A3 Turbo I4 1.8L 40 TFSI S-Line with the same mileage is listed for AED 40000. Considering the car's age, mileage, and condition, I adjusted the price downwards from the listed price to reflect a more realistic market value.
