The Opel GT, of which 103.463 examples left the factory between 1968 and 1973, always was a doubtlessly desirable car. In its homecountry, Germany, it still is well known for the slogan "Nur Fliegen ist schöner" - "Only flying is better.". More than 50.000 cars were exported to the USA, though, where it was known as the "Baby-Corvette". As you can see in these pictures here, not all of them survived. Nevertheless, the Opel GT is a popular classic today, with good examples reaching prices of 25.000€/30.000$. So, even the examples above and below probably are still worth some money. Most of them would require much more money to restore them, though.
