To estimate the price of the 2015 Audi A4 25 TFSI I4 1.8L Turbocharged 30 TFSI (Base) with 105300 km mileage and average condition, I considered several data points. First, I looked at the selling prices of similar cars: a 2015 Audi A4 2.0 I4 with 119300 km sold for 41000 AED, a 2015 Audi A4 2.0L Turbo I4 with 45300 km sold for 36000 AED, and a 2013 Audi A4 I4 2.0L Turbocharged with 121910 km sold for 21500 AED. The closest match in terms of variant and condition is the 2015 Audi A4 2.0L Turbo I4 (30 TFSI Base) which sold for 36000 AED. Considering the higher mileage and average condition of the target car, I adjusted the price downwards. Additionally, an offer accepted for a similar 2015 Audi A4 1.8L I4 with 120010 km was 27000 AED. Listed prices for similar cars range from 29000 AED to 35000 AED, but these are generally higher than actual selling prices. Taking all these factors into account, I estimated the market price accordingly.
