For a new/unproven platform, the 3-years/unlimited-miles warranty is gold if you ask me. I believe many, if any or all, major & notable problems/issues/failures will manifest during that time period on a properly & well driven MP4-12C.
FWIW, I'm not fully versed w/ the Ferrari 7-year service/maintenance program. Personally speaking, I believe there plausibly would be more to it than meets the eye w/ regards to consumables, wear-&-tear, replacement/repairs (based on similar service/maintenance programs & warranties by other manufacturers). Point being, shop invoices get padded, one way or another, even w/ routine service/maintenance. A gasket or seal here, a sensor or relay there. Part(s) being less than a c-note, but at least grand if not many in labor, exclusive to the service/maintenance agreement. Fluids, filters, inspections are a pittance & kinda/sorta not really all that much of a "freebie" that people make them out to be. Woo-hoo, lookie I got free wipers & they topped off my coolant! Oh wait, I owe $2,500 for the leaking valve-cover gasket & cam seal...
I'd prefer to have a solid, well designed/engineered offering out-of-the-box w/ respectable reliability/dependability sans inclusive maintenance/service plan, rather than marginal or questionable build-quality yet coming w/ an inclusive maintenance/service plan.
