I have owned a 2003 Vectra from new. All of the springs front and rear have failed in the last two years not to mention the shock absorbers. It is obvious that inferior materials have been used to save cost on what is quite an expensive car. I have been lucky that I experienced no failure at speed, which could be fatal on say the motorway at 70mph. The car has been serviced in accordance with the manufacturers recommendations and used for most of the time with driver only on good roads. I have owned and used company cars over forty years and never experienced suspension failures of any type whatsoever. If we were talking about an aircraft the manufacturer would be forced to correct what is potentially a lethal error. I will never buy, hire or recommend a Vauxhall car. GM deserves to go bust.
