The GT was launched in 1968 with a 60-bhp, 1100cc, OHV four-cylinder engine, and the 1897cc “high-cam” engine, which developed 90 bhp and gave quite a bit more performance. In all, 103,373 GTs were built, with about 70,000 coming to the U.S. Only 3,573 were fitted with the 1100cc engine.

Tne unusual feature of the Opel GT is the operation of the pop-up headlights. They are manually operated, by way of a large lever along the center console next to the shifter.
Unlike most pop-up headlights, they both rotate in the same direction counterclockwise from inside the car about a longitudinal axis.
One standard joke about GT owners was that you can easily spot them due to the heavy muscles on their right arm built up by using the lever to pop up the headlights.
The headlights were rotating 180 degrees i.e. half a turn. This meant that whenever you want your headlights to be sticking out from the car, all you had to do is to pull the lever on the inside and they turned nicely and smoothly.
