All our measuring instruments (especially calipers, paint thickness gauges, and refrigerant pressure gauges) are calibrated quarterly according to ISO quality management system requirements to ensure the data we provide you is objective, accurate, and reliable.

We will directly check the registration certificate (the big green book) and count the number of changes.

We will proactively provide a third-party inspection report (such as from Check Doctor), support customers in re-inspection at the store, and promise "return of major accident vehicles."
