To estimate the price of the 2017 Audi A6 35 TFSI I4 1.8L Turbocharged, I first considered the selling prices of similar cars. The most relevant data point is the 2016 Audi A6 1.8L TC i4 35TFSI with a selling price of 47100 AED, sold on 2023-12-29, as it has the same engine and similar condition. The 2016 Audi A6 2.8L V6 with a selling price of 61000 AED, sold on 2023-10-08, is less relevant due to the different engine size. The 2015 Audi A6 Quattro 2.8L V6 TC sold for 35000 AED, but it is older and has a different engine. The 2018 Audi A6 55 TFSI sold for 600000 AED is an outlier due to its different variant and likely error in data. The accepted offer for a 2017 Audi A6 35 FSI V6 2.8L AWD at 52000 AED on 2024-09-21 provides a useful reference, but it has a different engine. Considering the 2016 model with the same engine sold for 47100 AED, and accounting for one year of depreciation, I estimate the 2017 model to be slightly higher due to being a year newer and in good condition.
