To estimate the price of the 2020 SsangYong Tivoli I4 1.6L Base (FWD) with 138000 km mileage, I considered the listed prices of similar cars. The 2020 SsangYong Tivoli I4 1.6L Turbo Charged with 58306 km is listed for SAR 42000, and the 2021 SsangYong Tivoli I4 1.6L Base (FWD) with 28000 km is listed for SAR 43500. Given the higher mileage of the target car (138000 km) compared to these listings, I adjusted the price downwards. The significant mileage difference suggests a considerable depreciation. Assuming a depreciation rate of approximately 20-30% due to the high mileage and average condition, I estimated the market price accordingly.
