To estimate the price of the 2015 Audi A4 2.0L 40 TFSI (Mid) with 90500 km mileage, I first considered the selling prices of similar cars. A 2015 Audi A4 2.0 I4 45 TFSI Quattro (Top) with 119300 km sold for 41000 AED, and a 2015 Audi A4 2.0L Turbo I4 30 TFSI (Base) with 45300 km sold for 36000 AED. A 2015 Audi A4 25 TFSI Turbocharged I4 1.8L 30 TFSI (Base) with 105300 km sold for 25500 AED. The target car is a mid variant, so its price should be between the base and top variants. The accepted offer for a 2015 Audi A4 1.8L I4 30 TFSI (Base) with 120010 km was 27000 AED. Listed prices for similar 2015 models range from 28000 AED to 46500 AED. Considering the target car's mid variant and average condition, I estimate its market price to be slightly higher than the base variant but lower than the top variant, around 32000 AED.
