Hello, my MINI was registered on 22.06.2011. Now I received a letter from my friend, in which I am advised to have my vehicle checked again before the 2 year warranty period expires. To this end, a warranty extension of 12 months is offered for 229,00 EUR, which protects against mechanical and electronic defects. What do you have here for experience? At the convertible useful? Thank you for your feedback, Kris
