Living up North our roads can be liberally sprinkled with copious amounts of corrosive rock salt. I do believe it has become a 'finer' salt that is used today, hopefully causing less bodywork damage than the ghastly old orange coloured stuff which really did resemble 'rocks' and more readily damaged your paintwork before getting to work in earnest on the underside. Having said that I am sure vehicles will be far better protected than they were say a decade or two ago, particularly in obviously vulnerable areas.

Do you have any general advice and/or assurances on this specific aspect of winter motoring, long-term vehicle integrity and safety being absolutely paramount? Or do we have to try and replace the car every three or four or five years before the corrosion gets hold? Being semi-retired we try not to use the car when the roads are covered in ice and snow or when freshly gritted or (much) more so when it has rained on 'salty' roads,
