Short answer is yes as that's what TVR among others have done in the past.
Not familiar with the Kingspan you mention, but polyurethane foam is certainly used for this because it's very easy to shape with surforms etc.
You buy this in sheets/blocks, glue them together to form a rather boxy car shape and then sand to the shape you require.
Think most major fibreglass suppliers should sell it.

As above posts... the short answer is, yes, it's fine.
There's a book called 'Building and Flying Your Own Plane' (sorry, can't remember the author at present) that has detailed information on building mould-free composite structures by laminating fibreglass or carbon fibre over rigid foam, then getting a final surface finish by pouring a 'slurry' of microballoons and resin over the laminate. This system has been used for some of Burt Rutan's aircraft (eg. the VariEzi) and this website gives a lot of information about a car that is constructed using the same technique.
