To estimate the price of the 2015 Nissan X-Trail I4 2.5L S AWD (7-Seater) (Mid+), I considered several data points. First, I looked at the selling prices of similar cars. The 2015 X-Trail with 169076 km in good condition sold for 49000 SAR, and another 2014 model with 144700 km in average condition sold for 25000 SAR. A 2016 model with 233000 km in average condition sold for 34500 SAR. The 2015 model with 148000 km in average condition sold for 44500 SAR. Given the higher mileage (260000 km) and average condition of the target car, I adjusted the price downwards. I also considered the listed prices of similar cars, which were 39500 SAR and 41500 SAR, but these are generally higher than actual selling prices. Based on these factors, I estimated the market price accordingly.
