Welcome to the world of The Essence Of The Car.
This is different concept in the presentation of scale model vehicles. Instead of the high level of detail usual in the die cast ranges, these models present the vehicles in their basic form.
All are made to the standard collector's scale of 1/43 and each model carries a serial number and is accompanied by a certificate authenticity.
They have been described in different ways, such as sculptures or being like the original clay model that the vehicle manufacturers make as part of their development programmes. 
All of the master models are made in house by hand. When those are complete, the necessary moulds are made, again in house, and any production can begin.
All of the models are then finished by hand.
They are all available from David at http://www.theessenceofthecar.co.uk click through to the Saab Collection page.
