To estimate the price of the 2014 Audi A8 L TFSI Quattro V6 3.0L Turbocharged 60 TFSI (Top) with 173500 km mileage, I first considered the most relevant selling prices. A similar car with 148500 km sold for 45500 SAR on 2024-10-05. Another with 231500 km sold for 49500 SAR on 2023-11-19, but it was in good condition. A 2013 model with 220000 km sold for 41099 SAR on 2023-08-13. The 2012 model with 148500 km sold for 33724 SAR on 2024-10-02. The listed prices for similar cars range from 47000 SAR to 65000 SAR, but these are generally higher than selling prices. Considering the car's average condition and mileage, I estimate the market price to be slightly lower than the recent sale of a similar car with less mileage, around 45500 SAR.
