there is two types of warranties,
1. original car warranty
2. maintainance warranty.

1. and 2. carry over to 2nd owner. however, if the 2nd owner wishes to extend the warranties, he can only extend 1.

in other words, the maintainance warranty can only be extended by the original owner.

anyone can correct me if im wrong.

take care,
mustafa
