I'll have to go with the original car manufacturer. They've made a bunch of terrible cars, sure (who hasn't in a fiat world, no pun intended). A 2006 Focus I owned was the worst car ever (reliability wise). But they also made the original Mustang. I have a '99 Cougar (labelled as Mercury in the US) back in Estonia, a sufficiently powerful, lovely and cheap car. The 2011 Falcon XR6 I owned while I was in Australia is hands down the best car I've ever owned (not that I've ever owned any especially extraordinary cars):

I have a 2012 Jaguar XF at the moment, which is also a great ride and an even more beautiful car than the Falcon, but there are a bunch of small details which make me prefer the Falcon over the Jag.
