To estimate the price of the 2021 Mazda CX-30 2.0L URBANE Elite 2WD (Base), I first looked at the selling prices of similar cars. The 2021 Mazda CX-30 2.0L TC i4 Urban AWD (Top) with 44200 km sold for AED 78000 on 2023-10-06. Given that the car in question is a base model and has higher mileage (57516 km), its value should be lower. The 2022 Mazda CX-30 2.0 i4 Urban AWD (Top) with 9100 km sold for AED 85000 on 2023-12-18, but this car is newer and has much lower mileage, so it is not directly comparable. I also considered the accepted offer of AED 78000 for a similar 2021 model with 44200 km. For listed prices, the 2022 Mazda CX-30 2.0L MID Elite 2WD (Base) with 63647 km was listed for AED 82990, and the 2023 Mazda CX-30 2.0L URBAN Elite 2WD (Base) with 14110 km was listed for AED 84995. Given the higher mileage and average condition of the car in question, I adjusted the price downwards from these listings. Taking all these factors into account, I estimated the market price accordingly.
