I've never owned a brand new vehicle with a factory warranty so clueless ako dito. How does the casa know na pinagawa/pina-PMS sa labas yung sasakyan? I don't suppose may sticker yung mga bolts na nasisira or nabubutas kapag ginalaw.
I guess that's the biggest draw of casas. A lot of people don't know much about car maintenance so if they have deep enough pockets, they pay for the premium of the factory warranty and letting the casa take care of the rest. The casa, in turn, take advantage. Not all of them, of course.
Slightly OT: I always enjoy reading Deakin's articles. Never a dull paragraph, kaya enjoy basahin from start to finish.
