I started by examining the selling prices of similar cars. The 2021 Nissan Sunny I4 1.6L S A/T (Base) with 119,000 km sold for 31,500 SAR on 7 Oct 2024, and another with 107,400 km sold for 40,000 SAR on 2 Jul 2024. The 1.6L SV (Mid) variant with 46,000 km sold for 34,000 SAR on 23 Oct 2024. The car to be estimated is a 1.5L S A/T (Base) with 85,127 km. The 1.5L engine typically has a lower market value than the 1.6L. I also considered listed prices: a 1.5L S A/T (Base) with 75,000 km was listed for 35,000 SAR, and another with 127,500 km was listed for 27,000 SAR. The 1.6L S A/T (Base) with 119,000 km was listed for 31,500 SAR. Considering the mileage and engine size, I estimated the price slightly lower than the 1.6L models but higher than the 1.5L with higher mileage.
