First, I considered the selling prices of similar cars. A 2016 Audi A8 3.0L TC V6 with 75000 km sold for AED 103149 in July 2023. A 2015 model with 111000 km sold for AED 42000 in April 2024, and another 2015 model with 95500 km sold for AED 77500 in August 2023. The 2016 model is closer in year and condition to the car in question, but the mileage is significantly lower. Next, I looked at the offer accepted for a 2016 Audi A8 3.0L TC V6 with 138500 km, which was AED 67000 in September 2023. This is a good reference point as it is close in mileage and year. For listed prices, a 2016 model with 119500 km was listed for AED 72000, and another with 167500 km was listed for AED 67000. Considering the car's mileage of 142500 km and its good condition, I estimate the market price to be slightly lower than the accepted offer and closer to the lower end of the listed prices.
