forza horizon 2 pre-order

i pre-ordered the game but only got the ferrari cali nothing else can someone help find out what went wrong plz

Nothing went wrong. Certain stores had exclusive cars for pre-ordering the game with them (I can’t remember who did what but I’m sure someone on here does), for instance I ordered my copy from GAME in the UK and got the Ferrari California as a pre-order bonus.

I pre ordered on amazon uk and got some BMW , amazon emailled me the code 24 hours before the release date

Were you expecting something else?
