Any new Mac comes with one year of standard warranty, any new Mac can have its warranty extended for another two years (thus three years of warranty since purchase) via buying Apple Care. There is not a degree of how much Apple Care you buy, there is only a degree of what Apple Care you buy, since there is Apple Care for the iPhone, iPad, iMac, Mac mini and so on.
You need the standard Apple Care for a MacBook Pro, which currently costs 349 USD.
