These cars have promised much and have delivered squat.
This car sounds like a bit of a dream –it was built by one of the most successful race manufactures ever, Prodrive, and designed by the legendary Peter Stevens. They trotted out their prototype on Top Gear and that's the last anyone has seen of the P2.

This car made its debut at the British International Motor Show back in 2008 and still is yet to go into production. Interestingly, this car was developed from the Ronart Lighting from 1999 of which only six were made.

With a mahogany body, engine and front bumper from a BMW 6-series, and hydropneumatic suspension from a Citroën CX the Cumberford Martinqiue made it all the way to the cover of Car & Driver, but not into production. Ah, the '80s.

Vector is an automaker that has been borderline vaporware for its entire existence, but their latest WX-8 with approximately zero produced is true vaporware. At least the WX-8s website is great.

The story of the Dale is one of the most incredible in automotive history. I'm not even going to attempt to do it justice so just read Jason's take on it and you'll know why it's number one.
