Which of the following actions is required when creating an estimate?

Leaving a copy of the estimate with the shop or owner is crucial in the process of creating an estimate for motor vehicle repairs. This practice ensures transparency and keeps all parties informed about the projected costs associated with the repairs. It allows the shop, owner, and appraiser to maintain clear communication regarding the scope of work and any necessary approvals that may be needed before proceeding with repairs. Having a documented estimate reinforces accountability and helps in resolving any future disputes regarding costs or the specifics of the work to be performed.

In contrast, providing a warranty for repairs, while important for ensuring quality of work, is not a strict requirement during the estimating phase. Using only new parts can be an option, but estimates may also include used or refurbished parts when applicable, depending on the owner's preference and the nature of the repairs. Obtaining quotes from multiple repair shops can be beneficial for cost comparison, but it is not a mandatory step in the estimation process itself. The primary requirement is to ensure that all parties involved have a clear and agreed-upon understanding of the estimate, which is achieved by leaving a copy with the concerned parties.
