The used car inspection is not guaranteed because the vehicle is fully assembled for the inspection and the inspector cannot see the internal components of the vehicle, including the transmission or the engine. There is the possibility of impending failures that are not evident at the time of the inspection. In other words, if it is not failing at the time of the inspection, we will not know that it is failing. Therefore any used car inspection cannot be guaranteed. Lemon Squad always recommends to see the vehicle to verify it meets your expectations before purchase.
