To estimate the price of the 2014 Audi A8 L TFSI Quattro V6 3.0L Turbocharged, I first considered the selling prices of similar cars. A 2014 Audi A8 V6 3.0L with 231500 km sold for 49500 SAR, and a 2013 model with 220000 km sold for 41099 SAR. These cars have higher mileage than the target car, suggesting a higher value for the target car. A 2015 model with 81000 km sold for 89000 SAR, indicating a higher price for newer models with lower mileage. The listed prices for similar 2014 models range from 50000 to 76500 SAR, with the closest match being listed at 63000 SAR. Considering the target car's mileage of 148500 km and average condition, I estimate its market price to be slightly lower than the 63000 SAR listing, but higher than the 49500 SAR selling price of a higher mileage car.
