I can totally empathize with the many contributors to this forum whose car purchase has turned into a nightmare. As to the financial loss, think of it like divorce--it's gonna cost you a bundle to leave, but your sanity is more important than the money.
Of all the cars I have owned the best have been my 1995 Subaru Imprezza (a small tank), the 2004 and 2007 BMW's* and the 2011 & 2013 Focus' (except for Sync hiccups).
*BMW had high pressure fuel pump issues on the 2007 335i's. They immediately replaced the pumps and extended the warranty to 100,000 miles.
In addition, both of my Ford dealers have been great. I've had a couple of Sync issuers in the 2013 mostly involving it's ability to process voice commands with Mobil Apps, so the dealer is replacing the Sync module.
