A trolley (30) for use with a frame-straightening bench (10) and allowing for moving a vehicle into the bench (10) for initial repair; moving the vehicle out of the bench (10) and into holding area to allow for curing or other time-consuming repair processes or operations, thereby making the bench (10) available for other uses; and moving the vehicle back into the bench (10) for additional repair or final confirmation of a previous repair. A repair jig (140) is coupleable with the trolley (30) for facilitating the alignment and otherwise proper positioning of a portion of the vehicle being repaired. The trolley (30) can also be used with a lift (2072) to separate the vehicle's body from its frame (2010).
