Can anyone tell me if there is a way for me to obtain the Gallardo Superleggera now that the game is out and I didn’t preorder it from whatever specific retailer it was that was offering it?
Well I think I made the best deal ever with Amazon (Germany) 
I preordered the Day One Edition and got 3(!) Pre-Order cars:
BMW M6, RS4 Avant, Gallardo Superleggera
- Day One cars
Dito 
Was a great deal, three cars from Amazon, three cars from the Day One Edition.
Viel Spaß noch.^^
