Gas Guzzlers Extreme Answers for Playstation 4

2 cars still not unlocked?

I played through the entire career and won all tournaments, bought all cars, and even maybe unlocked all tracks. But 2 cars: the Kaiju GTR and the Fordiac Bandit, are still locked. Is there a special accomplishment I haven't noticed to unlock these, or were they part of a pre-order special deal I missed?
