'Purists' are looking for cars that conform as much as possible to the original cars: aluminum bodies that appear as similar as possible to the originals, aluminum interior panels, original-appearing dash, 90" wheelbase, bottom-hinged brake and clutch pedals, etc.

There are many who are more interested in a car that looks like a Cobra, but is perhaps easier to build, own and maintain. That probably means moulded fiberglass interior, parts which are readily available, etc. This market is probably much larger than the 'purists' category and therefore more market demand. Potential customers would also include those looking for longer wheelbase cars.
