To estimate the price of the 2015 Audi A6 I4 2.0L Turbocharged TFSI (Mid) with 130000 km mileage and average condition, I considered several data points. First, I looked at the selling prices of similar cars. The 2014 Audi A6 2.8L V6 with 140850 km sold for AED 33900, and the 2016 Audi A6 2.8L V6 with 142960 km sold for AED 61000. The 2015 Audi A6 Quattro 2.8L V6 with 185100 km sold for AED 35000, and the 2016 Audi A6 1.8L TC i4 with 131000 km sold for AED 47100. The 2016 Audi A6 3.0L V6 with 167000 km sold for AED 37500. The 2014 Audi A6 with 95000 km sold for AED 32000. I also considered offers accepted by sellers: a 2015 Audi A6 2.0L TC with 140900 km had an offer accepted at AED 38000, and a 2015 Audi A6 3.5L V6 with 174000 km had an offer accepted at AED 35000. Additionally, a dealer sold a 2015 Audi A6 with 133000 km for AED 30600. Given the car's average condition and mileage, I weighted the most recent and relevant data points, particularly the dealer sale and accepted offers, to arrive at the final estimate.
