I have found over the years that if you keep a vehicle long enough, you will recuperate the initial cost of a good warranty and then some every time.
I bought the Lifetime Max plan when I bought my truck and it was $1900 with a $100 deductible and that's forrrrrevvvvvver!
I intend to keep this truck for a minimum of 10 years and hopefully longer. I am POSITIVE that I will save that $1900 or more at some point.
If I'm amazingly lucky and the truck never breaks bad enough to recoup., - I have had good peace of mind, which has a large enough value in itself
