18: Oldsmobile Aurora
There was a time when the Oldsmobile brand was at the forefront of automotive design and innovation. Sadly, the 1990s were the beginning of the end for the brand as we know it. GM was heavily into badge engineering cars at this point. Oldsmobile had no unique cars that they could call their own. But in one final hurrah, GM designed the Aurora, which was intended to be a high-end futuristic car. It was said the plan internally was to branch the Aurora off as its own brand, but this never came to fruition (via Hemmings).

The Aurora was a beautiful car released at a time when automakers slowly moved away from boxy styling. The powerful Northstar V8 engine could compete with the best Germany had to offer. The interior was decked out with all kinds of new technology, most of which we take for granted these days. Sadly, it wasn’t enough to preserve the brand, and the Aurora was killed off with the rest of the Oldsmobile brand in 2004.
