Is that interior held in place with drawing pins? I don't wish to sound like a chav, but my first thoughts were that the motor needs to be LOWERED...
See that Karmann turned their hand to Beemers a couple of years later... http://www.carstyling.ru/cars.1976_BMW_Karmann Asso di Quadri.html It's no wonder Karmann went bust. That is fuuuuuuugly.
awesome blue paper/white pastel/pencil rendering, typical italdesign, do one design then try and sell it to loads of different manufacturers, Karmann are manufacturers, not designers. it's the same designer of the mk1 golf, lotus esprit, etc
