It's been about 3 months into my purchase of my 2006 SS, now has 67,000km and power train will expire in June/2011 or 100,000 km. I can purchase an ext warranty bumper to bumper for $1800 from Ensurall which will take me to 170,000km or June 2015. Should i buy this or not? am i going to get stiffed when the time for a claim comes saying that its maintenance and not repair? I am not very mechanically inclined so i will get all the work done at local garage or deale. I don't know what kind of repairs can i expect to go wrong and how much they will be over time to June/2015. any suggestions advise would be helpful.
