A few nice auto mold design images I found:

Transformer Cars of Frant, Great Britain, was founded in 1986 by Gerry Hawkridge and is best known for producing replicas of the Lancia Stratos. Most were based on Lancia Beta components and were sold as the Transformer HF2000; versions with Alfa Romeo V6 engines or Ferrari V6 and V8 engines were sold as the Transformer HF3000.
A more prestigious project was the Ferrari 500 Mondial Series 2 replica presented by Transformer. It was a remarkably life-like copy of this rare and very valuable car and to this day Ferrari experts discuss which original was used to make the moulds. The chassis is a tubular frame fitted with a fiber glass body and aluminum hood, doors and boot-lid. This version also shows extensive use of aluminum in the interior. Power comes from a 2 Litre 4-cylinder Alfa Romeo unit (in this case an engine from 1970 was used). Expert craftsmanship and attention to detail made the Transformer SD 500 a close match to the original.
In fact, the myth goes that after somewhat more than a dozen of these replicas were made Ferrari bought the designs and the molds and destroyed them. Certain is that only a few were made. Gerry Hawkridge went on to establish Hawk Cars in 1991 and Transformer closed its doors in 1996. The production of Lancia Stratos replicas was transferred to Hawk Cars and continues to this day.
