Why ???? It's funny, have seen a few when I was a student in England. The build quality is absolute ***** and you can spot them a mile off. They have quite a network, see their techincal website. There is even a dude in there who has a 993 powered Covin.
911s, are relatively inexpensive, buy the real one why a replica. Think it's dumb.
