Few people know the company Glassport Motors and hardly more have ever seen a GSM Flamingo. The GT coupé originated in South Africa and was developed together with its predecessor Dart/Delta by a very talented trio. Despite excellent driving characteristics and an unmistakable design, the project was not successful and only a few of these cars are likely to have survived. This report tells the story of GSM and shows the Dart/Delta and Flamingo models in many pictures and in the sales literature of the time.
