I started by looking at the selling prices of similar cars. The most relevant data points are: a 2015 model with 176000 km sold for 52500 SAR, a 2015 model with 201000 km sold for 60500 SAR, and a 2016 model with 224500 km sold for 62000 SAR. Given the target car's higher mileage of 253000 km, I adjusted the price downwards. The 2013 model with 314000 km sold for 41000 SAR, which also influenced my estimate. The listed price of a similar 2015 model with 282000 km was 48000 SAR, but this was higher than the actual selling prices. Considering all these factors, I estimated the price accordingly.
