Ok, I see that this thread has turned into the ritual humiliation of somebody who has dared to do something stupid.
Most likely the lower suspention arm cracked/broke causing the steering loss, which could have been caused by many different factors. Although probably induced by wreckless driving in public car parks etc... In many ways it was unlucky it happened on the road, as it'd probably have caused less damage to the car in a car park (exept perhaps for the close proximity of the people enjoying the action)
And just before you all have a go at me... I don't particularly like cruises, or some of the people who go to them, nor do I go to them, my car isn't 'barry', and burberry isn't my favourite brand for hats. But each to their own, and anyway who hasn't done a cheaky hand break turn in a slipery car park when all is quiet and nobodys looking?
Shelly: Hope your mates car gets fixed soon, and nobody was hurt.
