30. 1969 Porsche 914
You might have seen one of these at a car show, but other than that this was not a popular model. What made the 914 so bad? For starters, the engine was severely underpowered, which the company had hoped the car would make up forgiven its lightweight design. You can also tell that there was a good deal of outside design help that went into the 914.

Aside from that, the 914 came with either a choice of a flat-four or flat-six engine. Horsepower totaled around 110BHP, which was nothing amazing. A well-maintained 914 will set you back a pretty penny. Parts for this car are scarce, and only certain mechanics can work on them.
