To estimate the price of the 2016 Nissan Sunny I4 1.5L SV (Mid) with 275000 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2016 Nissan Sunny I4 1.5L S A/T (Base) with 164000 km sold for 22000 SAR, a 2018 Nissan Sunny I4 1.5L SV (Mid) with 226000 km sold for 25500 SAR, a 2016 Nissan Sunny I4 2WD SV (Mid) with 58000 km sold for 26000 SAR, and a 2014 Nissan Sunny I4 1.5L S A/T (Base) with 159000 km sold for 22500 SAR. Given the higher mileage of the target car, I adjusted the price downward. I also considered listed prices: a 2016 Nissan Sunny I4 1.5L SV (Mid) with 294000 km listed for 23000 SAR, another with 237200 km listed for 25500 SAR, and another with 226000 km listed for 24000 SAR. Taking into account the higher mileage and average condition of the target car, I estimated the market price accordingly.
