Hi Alan I would agree...get a second opinion, possibly their equipment could be faulty or out of calibration? Additionally, there are so many other factors that can affect the geometry when being measured....loading of the car, weight distribution, worn suspension components (bushes, springs, dampers, link arms, etc). I would imagine if any suspension components are damaged by the pot hole then it would be a case of replacement of the damaged parts before re-aligning. Please let us know how you get on.
