I always liked the Tapiro. And not at all because it was built on the Porsche 914/916 mid-engine platform and I actually owned a 914. It was, to my way of thinking, a truly interesting design exercise. On the other hand, a production car of that design would have been impractical due to its low height (the only vehicle a driver could see over would be something similar to the Tapiro itself) and lack of storage space (unlike the Tapiro, standard 914s had storage space suitable for travel; I crossed the USA twice in mine).
Giugiaro also had a major hand in the styling of the DeLorean DMC-12, which resembles the Tapiro.
