To estimate the price of the 2011 Audi A5 2.0L I4 45 TFSI S line (Top+), sedan, with 209688 km mileage and in bad condition, I considered the following data points: 1. A 2011 Audi A5 2.0L I4, coupe, with 171300 km mileage, average condition, and 40 TFSI S line (Mid) variant sold for AED 17500 on 2024-03-10. This car is in better condition and has lower mileage, so the price should be adjusted downwards. 2. A 2013 Audi A5 2.0L I4, 40 TFSI S line (Mid) variant, sedan, with 193000 km mileage listed for AED 29000. This car is newer and in better condition, so the price should be adjusted downwards. 3. A 2010 Audi A5, 45 TFSI Quattro (Top) variant, coupe, with 190000 km mileage listed for AED 21500. This car is older but in better condition, so the price should be adjusted downwards. 4. A 2013 Audi A5 S line 2.0L I4, 45 TFSI Quattro (Top) variant, sedan, with 244200 km mileage listed for AED 25000. This car is newer but has higher mileage, so the price should be adjusted downwards. 5. A 2011 Audi A5 2.0L I4, 40 TFSI S line (Mid) variant, coupe, with 171300 km mileage listed for AED 22000. This car is in better condition and has lower mileage, so the price should be adjusted downwards. Considering the bad condition and higher mileage of the target car, I estimate its market price to be significantly lower than the listed and sold prices of similar cars.
