There are apparently a few diehards who still like the Yugo, though Cthulhu alone knows why.
An oddly reassuring aspect of auto culture: No matter how disastrous, disreputable, or famously failed a vehicle might be, every mass produced car seems to have at least a small contingent of devoted; indeed, fanatical fans. There is, for example, a Vega car club, a very active AMC Pacer subculture, and even, so help me, a Pinto car club. Nothing goes to waste, not even misguided enthusiasm.

(As a big fan of the Citroen 2CV, I might be accused of a double standard, since it is even uglier than the above named products, but nobody could call it a failure.)
