The Omni was a compact car sold before the K-Car. The compact Dodge had many similarities to other compact cars from this era. The boxy design was cheap to build and cheap to buy. Initially, the Omni was a hot seller for Dodge until there were reports of gas tank fires. This chain of events negatively affected the sales of the Omni (via Car and Driver).
The Omni had a special-edition Shelby model, but that wasn’t enough to save the nameplate. Dodge moved on after the success of the K-Car era. The Omni is seldom seen on roadways anymore and with good reason. Between the build quality and the lack of reliability, the Omni was a less-than-stellar choice.
