I'm no expert either. But...
1) Fork shape not correct (aero profile at the head tube junction on the real Dogma2)
2) No front derailleur hanger
3) No holes on down tube for internal cables
4) Rear derailleur hanger wrong
5) Seat tube collar wrong
6) BB most likely wrong
And on and on.
Besides, why would someone be selling a brand new real Dogma 2 that lists for somewhere near $6,000 for a mere $2,000? That's the only question you really need to answer.
Run away. Fast.
