To estimate the price of the 2020 Audi Q3 S line I4 Quattro 2.0L Turbo 40 TFSI (Top), I first looked at the selling price of a similar car: a 2021 Audi Q3 Sline 2.0L I4 TC with 22000 km sold for AED 155000 on 2023-07-22. Given that the car in question is a year older and has higher mileage (50000 km), I adjusted the price downwards. Next, I considered the listed prices of similar cars. A 2020 Audi Q3 40 TFSI (Top) with 22000 km was listed for AED 185000, but this is likely higher than the actual selling price. Other 2020 models with different variants and higher mileage were listed between AED 115000 and AED 139750. A 2021 model with higher mileage (78800 km) was listed for AED 121000. Taking into account the depreciation and the higher mileage of the car in question, I estimated the market price accordingly.
