The car to be estimated is a 2024 Changan UNI-T Turbo Charged I4 1.5L Elite (Base) with 15500 km mileage. The closest selling price data is for a 2024 Changan UNI-T Turbo Charged I4 1.5L SVP (Top) with 10000 km sold for 81500 SAR in July 2024. The 2023 model with similar specs but higher mileage (17300 km) sold for 71500 SAR in December 2023. The Elite (Base) variant is typically priced lower than the SVP (Top) variant. Considering the 2024 model's selling price and the depreciation from the 2023 model, the Elite variant should be priced lower than the SVP. The listed prices for 2023 models range from 66500 to 87000 SAR, with higher mileage cars listed lower. Given the Elite variant's lower trim level, a reasonable estimate would be slightly below the 2024 SVP selling price, accounting for the trim difference.
