To estimate the price of the 2019 Chevrolet Spark I4 1.4L LS (Base) with 57850 km mileage, I considered several data points. First, I looked at the selling prices of similar cars: a 2020 model with 41400 km sold for 27000 AED, a 2019 model with 133424 km sold for 17549 AED, and a 2017 model with 139500 km sold for 14500 AED. The 2019 model with higher mileage sold for 17549 AED, indicating a lower value due to higher usage. Next, I considered a dealer-sold 2019 model with 66667 km for 32295.75 AED, which is higher but from a dealer. For listed prices, a 2019 model with the same mileage was listed for 25000 AED, and similar 2020 models were listed between 28000-35990 AED. Given the average condition and mileage, I adjusted the price slightly lower than the dealer price but higher than the private sale of the high-mileage 2019 model.
