To estimate the price of the 2020 Suzuki Ertiga I4 1.5L GLX (Top) with 157000 km mileage, I started by looking at the new car prices. The 2025 Suzuki Ertiga 1.5L GLX is priced at SAR 78250. Considering a 10% annual depreciation, the 2020 model would be approximately 50% less, giving a base value of around SAR 39125. Next, I considered the offer accepted for a 2020 Suzuki Ertiga I4 1.5L GL (Base) with 118000 km at SAR 36000. Given that the GLX is a higher trim and the mileage difference, I adjusted the price upwards. The listed price for a similar base variant with the same mileage is SAR 35500, which supports the accepted offer price. Factoring in the higher trim and additional mileage, I estimated the market price accordingly.
