5571 indeed!
The quality is fine mostly, a few bits have annoyed me though. The black Technic pins with friction don't have any friction so the rear mudguards flap about a bit and it would be a disaster in a Technic model of you were relying on them for rigidity. There are a few noticeable places where the various between bricks are slightly too wide, and I've found two 1x1 round bricks with excess plastic around where the mould joined up. Also the old style Technic bushes don't mesh into each other like they should.
When it's finished I'll try and get round to writing a proper review, I've got a feeling more issues might crop up.
It was €87 with free shipping if I remember correctly. It is Lepin. Don't know what else they do in the way of old sets but there's nothing else I want that's so expensive that I wouldn't pay for the genuine article!
