First things first, my commiserations if this was a forum member and I hope nobody was hurt
However, as someone who has just swapped out his springs, coils, airbags and shocks (because they were all okay for MOT, but except one airbag where all either completely nadged or very tired)...I can't help looking at this RTC in Cumbria yesterday and the age of the car and wondering if it was a suspension issue.
This is a looong, national speed limited hill with swooping bends and a very healthy gradient. Therefore, it could have resulted from any one or combination of a number of contributory factors...but as I say, it just made me wonder.
