Okay I might of been in error. I thought you were talking about deformed lift points a lift uses. Not the jackpoints in the rocker panels. Can you clarify? Rusting there is an issue unless just surface from the protection being worn off by use. Deformation of a lift point could occur by various poor unpadded lift applications. I am not familiar with the 126 under carriage to be fair as well. If indeed the actual jackpoints are collapsing from corrosion that makes the car a slightly rust bucket type of proposition maybe.
