Porsche 919 Hybrid (2014), Audi R18 e-tron quattro (2014), and Toyota TS040 Hybrid are on sale to me at 600, 500, and 500 GC. Will buying any of these unlock Endurance Kings? If so, which one should I buy? I have only about 600 gc. I am far from 100%, so I am not sure if I should buy one now or postpone for later.
