To estimate the price of the 2023 Mazda CX-30 I4 2.0L High (Top) with 58000 km mileage, I first considered the selling prices of similar cars. A 2021 High (Top) variant with 33000 km sold for 70000 SAR in September 2023. A 2022 High-Black (Mid) variant with 46000 km sold for 70000 SAR in September 2024, but it was in average condition. The 2023 model is newer and has higher mileage, so it should be priced slightly higher than the 2021 model but similar to the 2022 model. The listed prices for 2023 High-Black (Mid) variants range from 75000 to 88000 SAR, with a 53000 km car listed for 75000 SAR. Considering the 2023 model's higher trim and mileage, I estimate its market price to be slightly above the 2022 selling price but below the higher end of the 2023 listings.
