To estimate the price of the 2014 Audi Q5 I4 2.0L Turbocharged 30 TFSI (Base) in bad condition with 171500 km mileage, I considered several data points. First, a similar 2014 Audi Q5 2.0L I4 30 TFSI (Base) with 161000 km in average condition sold for AED 25500 on 2023-12-31. Given the worse condition and higher mileage of the target car, I adjusted the price downwards. Another similar car, a 2014 Audi Q5 2.0L I4 30 TFSI (Base) with 175500 km was listed for AED 37500 but was delisted, indicating it likely did not sell at that price. Considering the accepted offer of AED 34000 for a 2014 Audi Q5 2.0L TC I4 35 TFSI (Mid) with 181500 km in better condition, I further adjusted the price downwards. Finally, the selling prices of other variants and conditions were also considered, but the most relevant data point was the AED 25500 sale, adjusted for worse condition and higher mileage.
