Custoca was an Austrian glassfibre specialist active from 1970 to 1986, initially operating as Custoca Kunststoffkarosserien in Leoben before relocating to Kraubath and continuing as Custoca Fiberglass Austria. The company was founded by Gerhard Holler and took advantage of its expertise in glassfibre construction to produce beach buggies marketed under the name Amigo.
Its other significant product was the Strato, a car whose styling was said to draw inspiration from the Lamborghini Marzal concept, although this influence was limited to its appearance. Beneath the glassfibre body, the Strato relied on a Volkswagen Beetle chassis with a rear-mounted engine. The design was later produced under licence in Switzerland as the Albar Jet, and an updated version of the model was sold as the Taifun.
Custoca also built the Hurricane, a coupé influenced by the styling of the Ford GT40, which was designed to fit onto a Volkswagen Beetle floorpan. Depending on customer preference, the Hurricane could be fitted with either Volkswagen or Volkswagen-Porsche engines.
