Open the used car engine cover and look at the two longitudinal beams of the entire engine room and check that they have no traces of welding or cracking. If this is an end or side impact accident, the frame is squeezed and bent or cracked and both require welding repair. If the condition of the lifting frame, you can check out the obvious, because the vast majority of car chassis, as the ribs pass before, you can determine whether there are any accidents through the ribs are not straight and strengthen the inspection.
