how is is that you can get unicorn cars? what do you have to do to get them in forza 4 and horizon?
There are no Unicorn cars in FM5
To get them in every game that has them come directly from the Devs which either host events are throw some giveaways in their news posts here on the forums (Only in the new’s section with a Dev as a openning poster so best not to spam other sections as that will not get you any unicorn cars)
