Hmm, I'd switch the Marussia B2 with the Hennessey Venom GT, not just because I want it, seeing as how how the Marussia would totally not qualify for A1 (more like A4), and Star relinked the Venom GT (which tends to be a sign that the developers are messing with it), it seems to be in high demand, and unlike any other car that can supposedly go faster than the Bugatti the Venom's speed is ACTUALLY confirmed, however, it might not, as I believe the Venom GT is not a hyper car. I can agree with the Zonda R (remember when Mitko was asking which sound mod sounded better?) and Corvette Stingray (only one I can think of really that would fit the role).
(Mentioned before as I don't feel like going to the last page to quote it) Actually, A Mercedes CLK-GTR would actually be good car, there is a model for one in Forza Horizon, as for the Murcielago, I'd like just a normal LP-640 to be perfectly honest, I don't particularly care about a spoiler on that car.
And the fact that the pack might be released this week is excellent news!!! I'm specifically excited for the LaFerrari, I've been wanting that one back for a while.
