For too many reasons, and I am happy to explain:
first of all the ENTIRE replica world is still totally unknown,people neither knows what a Cobra is down here( the few ugly 1970s pilgrims are usually sold at prices that sounds as an insult...)
Consider I was the FIRST italian joining this forum, and also the first (of 3 or 4 at today) one joining the gt40 enthusiast club.
For what about Ferrari we are in the most dangerous place where to have a ferrari replica,because the factory will seriously kill u and destroy the car nearly immediately(think also jail and public shame...

much more than if u will kill somebody..).
I own a modelling store, and ferrari looks seriously also at originality of models inside my shop.
I think me and the few enthusiast guys I know down here will be able some day to have a very little group of Cobra and gt40s,but surely NEVER a serious ferrari replica (there are anyway..the nicest 250 GTO replicas are done by ex-Ferrari hands too in Modena area...but nobody has to know this...and usually for sale around 1 milion dollar,and mostly for foreigners).
And from what I read around, also replica manifacturers always try change something in ferrari p4 shape,surely trying to avoid penal problems(no reason to change the perfection, right?)
If all this will happen here, be SURE u will have very very serious problems.
The matter is in Ferrari itself, because too important part of italian automotive history and tradition.
When u buy that, or simply drive that..u have a piece of ENTIRE italy art masterpiece,exactly as if u have a brick of Venezia.(holy sh**

I love gt40 and I am making my usual love declaration for maranellos a**holds...

)
And I agree with theme

but anyway love NF and Fran p4s too..
P.s: YES I mean wonderful p4s as your pictures one

...or as that nice one running around NY driven by a cool guy named Jim..
