Ask for parts and labour to be listed separately, with the proposed parts brand or supplier and any machining, fluids or programming. A low starting price may cover a scan or labour only.
Parts choices depend on the application. Compare genuine parts with identified compatible alternatives where available, rather than assuming every product described as OEM or aftermarket has the same origin or quality. The quote should identify what will actually be fitted.
Confirm the expected completion window, parts availability and what could change it. Major internal work may need dismantling, measurements and supplier lead time. Any revised scope needs to be explained before additional work proceeds.
Request the applicable written warranty for the exact work. Check parts versus labour coverage, time or mileage limit, exclusions and the procedure if a related symptom returns. No blanket warranty is implied by the budget table.
