To estimate the price of the 2019 Chevrolet Blazer I4 2.5L 3LT (Mid) with 83000 km mileage, I primarily considered the listed prices of similar cars. The closest match is a 2019 Chevrolet Blazer I4 2.5L 3LT (Mid) with the same mileage listed for AED 69000. Another relevant listing is a 2021 Chevrolet Blazer 2.5L I4 3LT (Mid) with 86200 km listed for AED 63000. Given the 2019 model year and average condition, I adjusted the price slightly lower than the 2019 listing but higher than the 2021 listing due to the older model year and similar mileage. The other listings of different variants and years were used to understand the general market trend but were not directly comparable due to differences in engine size and trim.
