To estimate the price of the 2012 Audi A4 I4 2.0L Turbo 40 TFSI (Mid) with 207650 km mileage, I considered several data points. First, an offer was accepted for a 2012 Audi A4 2.0L I4 30 TFSI (Base) with 216600 km for AED 20000 on 2024-03-12. This provides a baseline for a lower trim. Next, I looked at listed prices for similar cars: a 2012 Audi A4 I4 2.0L Turbo 40 TFSI (Mid) with the same mileage was listed for AED 20000 but not delisted, indicating it might not have sold at that price. Another 2012 Audi A4 2.0L I4 40 TFSI (Mid) with 235600 km was listed for AED 16000 and delisted in July 2024, suggesting it might have sold around that price. Considering these data points, the average price for similar cars in the market is around AED 18000 to AED 20000. Given the condition and mileage of the target car, I estimate its market price to be slightly lower than the higher end of this range.
