Most warranty contracts don't allow modifications. Dealers will tell you total BS to sell you something.
If you do buy a warranty, make sure it's an FCA warranty and not some aftermarket BS. And make sure it
has a ZERO deducible too. Paying 100 bucks for a covered problem is a ripoff, IMO!
I would take the money and put it into a saving account and be my own warranty administrator :yup:
