AMG options come in packages, while Porsche concentrates to charge you for every simple nonsense and ridiculous option which should be standard for what they're asking for with 2 missing cylinders out of the engine, and the very very strict and limited warranty (2~3 years depending on region & 4 years for USA + certain mileage) have they added service contract yet ? or is it still 'under consideration' ? not so confident with their engine reliability I presume
