A Pontiac Fiero
The Pontiac Fiero was a mid-engine sports car built on Earth during the late 20th century.
When the USS Enterprise crew went back in time to 1986, in effort to return humpback whales to the 23rd century, a Fiero was seen in traffic as the crew crossed the street, around the time that Captain Kirk was nearly run down by a car. Another Fiero was seen on the street near the plastics factory where Scotty introduced transparent aluminum to the 20th century. (Star Trek IV: The Voyage Home)
