just taken the T for its MOT and was gutted to realise it had failed on a broken rear spring just the point on the end of the bottom coil. Rang my local Renault dealer up for a price and was told that my car had the 'Extreme Pack' on it, and it would be £138+vat #-o . Now i have 2 questions, what the hell is an 'extreme pack'? and what is the actual difference between these springs and pattern springs that would cost me £25+vat?
