Well, the "odds" are that its a bad bet. They would not offer this if "on average" they were experiencing more than $1,500 in repair costs in the period covered. On an individual level, its insurance. If you have $200 in warranty repairs in five years, you lose. If you have $3,000 in covered repairs, you win. I usually do not buy warranties, but I did for my Suburban, and the entire hydra-boost brake system had to be replaced at 4 years, I won that one. I also had it on my 2002 RT/10, then I supercharged it(can you say voided?) and sold it before 3 years. Guess I didn't need that extra warranty.
