To estimate the price of the 2013 Lexus LS600 h V8 5.0L Hybrid Standard with 163000 km mileage, I considered the listed prices of similar cars. The closest match is a 2013 Lexus LS600 h V8 5.0L Hybrid Standard with the same mileage and specs listed for SAR 95000. Another relevant data point is a 2015 Lexus LS600 V8 5.0L Standard with 123000 km listed for SAR 132500. Given that the 2013 model is older and has higher mileage, its value would be lower than the 2015 model. Therefore, the most relevant data point is the 2013 model listed for SAR 95000. Considering the market trend and the fact that listed prices are generally higher than selling prices, I estimate the market price to be slightly lower than the listed price.
