To estimate the price of the 2015 Audi A8 L 50 TFSI Quattro V6 3.0L Turbo Charged 60 TFSI (Top) with 165000 km mileage, I first looked at the selling prices of similar cars. The most relevant data points are: a 2015 Audi A8 V6 3.0L Super Charged with 81000 km sold for 89000 SAR on 2024-05-14, a 2016 Audi A8 V6 3.0L with 171000 km sold for 59500 SAR on 2024-05-09, and a 2014 Audi A8 V6 3.0L with 231500 km sold for 49500 SAR on 2023-11-19. Considering the condition and mileage, the 2015 model with 81000 km sold for 89000 SAR is the closest match but has significantly lower mileage. The 2016 model with similar mileage sold for 59500 SAR but is a base variant. The 2014 model with higher mileage sold for 49500 SAR. I also considered listed prices: a 2015 model with 165000 km listed for 82500 SAR, another with 163000 km listed for 65000 SAR, and another with 182730 km listed for 98000 SAR. Given these data points, I adjusted for the higher mileage and condition to arrive at a fair market estimate.
