Its 8 years/ 80k, which is basically no warranty... how many cats die before 80k?
Then again, how many newer cars come with copper plugs? I almost took a picture of the plugs. They were original at 103k and worn so bad that there was almost nothing left on one of them. A cylinder was not firing for a long time. This car was owned by a kid in highschool who seemed to have changed the oil a lot. Again, probably just figured a newer car should be good to 100k with modern plugs. Especially a car sold as Eco, which insinuates that it is newer technology.
