Unlock Reward cars?

[andrethaiss]

Does anyone know any way in which i can unlock the special reward cars(me4-12, cobra concept) without having to do the challenges? I only cruise in hardcore mode and i never race, so is there any way that i can unlock them by modding files in the performance editor, and i play offline because i have mods so, can anyone suggest?

If you would play online you could see if there's one for sale, but you don't see that very often.

I don't know a way to unlock the cars in another way. And if there was one it would be illegal to discuss on here:p. Sorry, but you'll just have do the challenges.
