Thank you for purchasing your new insignia.
As you will be aware this vechicle is fast building a reputation for its high level of quality and safety standards and is part of our ongoing pregramme of continuous improvements.
We have have already introduced a number of minor specification changes and would like to offer you the opportunity to have your vechicle checked and brought up to the latest standard. this work is of course free of charge and should be completed within one working day.
Wondering if any VX people here had any clue what might of changed and what they will be doing to my car when I give them it as the letter doesn't state much more than the above?
