I analyzed the selling prices of similar used cars. The closest match is the 2015 Audi Q7 V6 3.0L with 247000 km, sold for 58000 SAR in good condition. Another 2015 model with 140000 km in good condition sold for 70000 SAR. A 2016 model with 101000 km in average condition sold for 72500 SAR. Considering the target car's higher mileage (231488 km) and average condition, I adjusted the price downwards. The 2014 model with 160000 km in good condition sold for 58000 SAR, which also supports a lower estimate for the target car due to its higher mileage and older year.
