To estimate the price of the 2019 Audi A6 55 TFSI S Line V6 3.0L 55 TFSI (Top+), I first looked at the selling prices of similar cars. The 2018 Audi A6 55 TFSI (Top+) sold for AED 600,000 on 2023-12-28, but this price seems unusually high and likely a typo. The 2020 Audi A6 40 TFSI I4 2.0L Turbo Charged sold for AED 75,000 on 2024-08-18. Given the significant difference in engine size and trim, this price is not directly comparable. Next, I reviewed the listed prices of similar cars. The 2020 Audi A6 45 TFSI Quattro (Top) with similar mileage is listed for AED 99,750. Other 2020 models with similar specs are listed between AED 99,750 and AED 129,750. The 2018 models with lower trims are listed between AED 55,000 and AED 89,120. Considering the 2019 model year, higher trim, and average condition, I estimate the market price to be slightly lower than the 2020 models but higher than the 2018 models.
