I have in the past always been an anti-extended warranty guy. However, when I bought my truck, the dealership had a offer I would have been crazy to refuse. They gave me an additional 3 year bumper-to-bumper, free oil changes for 6 years, free brakes, free suspension, free wipers, and couple other things I can recall off the top of my head...all for $2500. So basically, I'm pre-paying for the parts ahead of time, and getting the comprehensive warranty for free. The original price was $2900, but played a little hardball.
