The car to be estimated is a 2023 Kia Carens I4 1.5L 2.0L (Top) with 18000 km mileage. We have new car prices for 2025 models: the 1.5L EX is SAR 98900, and the 1.5L EX S1 is SAR 89700. Assuming a 15% annual depreciation, the 2023 model would have depreciated for one year. The 2023 price for the 1.5L EX would be approximately SAR 84165 (98900 * 0.85). The listed price for a 2023 Kia Carens 1.6L (Base) with 15000 km is SAR 77500. The 1.5L Top variant is likely more expensive than the 1.6L Base, so we adjust upwards from the base model's listed price. Considering the new car price and the listed price, the estimated market price for the 2023 1.5L Top variant is slightly higher than the base model's listed price.
