the thing is, in terms of quality of product, ignoring all of the figures, the noble has a long way to go until it reaches the standards of ferrari and the rest (the prices of which, ferrari especially are a little suspect in the first place)

if noble were to produce their own parts instead of raiding available parts bins, the cost of their cars would rise accordingly.

i would say the ferrari stradale comparison, is a bit unfair as you are comparing a car that has gone through a further stage of production from the standard road car that is rather high tech to begin with.
i think a more suitable comparison would be that of the noble vs a tvr (take your pick).
my reasoning is that tvrs are also british made, small volume, has bespoke parts made in house AND YET is still in the same price bracket as the noble.
