* Mechanic's experience: A more experienced mechanic will be faster.
* Condition of the car: If there's significant damage beyond the bumper cover itself (e.g., damaged underlying components, rusted fasteners), it will take longer.
* Availability of parts: If the mechanic needs to order parts, this will add to the overall time.
* Complexity of the removal/installation: Some vehicles have more intricate bumper removal procedures than others. While generally straightforward, unexpected complexities could arise.
Therefore, while 1-2 hours might be a reasonable expectation for a relatively straightforward job, it's best to allow for a longer time frame to account for unforeseen issues.
