It has nothing to do with build date. The Dart isn't a horrible automobile-- it was, however, designed to meet a high standard while it was manufactured to a very low one. Such a low standard was shown to be reality that the car couldn't be sold for a break-even price to the general public. The Dart is the cheaply-built, unreliable-- rushed-to-production-- car that neon haters always pretended the neon was. If my 2015 Dart makes it 12 years like my 1998 neon did-- I'll be handing out cigars and beers, because it will be a real reason to celebrate.
