Forza Motorsport 3 Unicorn Cars

For FM3, does anyone know how to get the Unicorn cars onto your save file WITHOUT a modded 360? I’ve explored a number of different programs the last few months, including WeMod’s Horizon, Ellipse, and Anarchy, and none of them have a unicorn adder for FM3 specifically. What’s weird is that Horizon can add them for FM4 and FH1, just not for FM3 :frowning:

Moreover, I’ve seen a number of threads on Se7ensins that offered to do this for people either for free or for a small fee by sending them your save file, so it seems like this was indeed figured out but it just never made it into the suite of modding tools out there. There were only three unicorns for FM3: (1) 1969 Chevrolet Camaro Super Sport Coupe; (2) 2002 Mazda RX-7 Spirit R Type-A; (3) 2006 Subaru Impreza S204.

Can anyone here shed any light on this and let me know if this was ever actually possible outside of a modded 360 console? Does anyone know why a unicorn adder was never included in Horizon despite there being one for both FM4 and FH1?

Edit: One possible explanation I had for the reason it was never added to Horizon was that in FM3 I believe, you could list Unicorns on the Auction House, so in its heyday, it was possible to get them that way, though still difficult. In FM4, however, Unicorns could neither be gifted nor listed on the AH. So perhaps demand for Unicorns were greater in the latter game since more folks missed out on them? Just a thought.
