To estimate the price of the 2018 Audi A8 L 55 TFSI Quattro V6 3.0L Turbocharged 60 TFSI (Top) with 88000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2018 Audi A8 V6 3.0L Twin Power Turbo with 104000 km sold for 160000 SAR on 2024-06-25, and a 2020 Audi A8 L 55 TFSI Quattro V6 3.0L Turbocharged with 47000 km sold for 195000 SAR on 2024-06-29. The 2016 Audi A8 V6 3.0L with 171000 km sold for 59500 SAR on 2024-05-09, but it is less relevant due to its older model year and higher mileage. Next, I reviewed listed prices: a 2018 Audi A8 L 55 TFSI Quattro with 88000 km was listed for 189500 SAR, and a similar 2018 model with 104000 km was listed for 168000 SAR. Considering the selling prices and the listed prices, I adjusted for the average condition of the target car and its mileage. The most relevant selling price is 160000 SAR for a similar 2018 model with higher mileage, suggesting a slightly higher value for the target car due to its lower mileage.
