I don't know, the old 10 lapper in Endurance Kings has the Porsche 911 RSR (2013) and Porsche 911 RSR (2014) cars in it. When they have been previously been offered for sale, it had a buy it now button, which unlocked Endurance Kings, it's regularly on sale:
 * List of sales so far - Every car on sale since 2013 ! Useful for planning to buy an expensive car.

You could cloud save, buy it and see, if your not happy cloud restore.

Did you win one of the 2015 LMP1 cars? Are you farming the new 10 lapper? If so you only need one 10 lapper, if not it's worth a try and buy the Audi, for R$ 3,200,000, in it's showcase event, you still need 320 GC and R$ 2,560,600 to upgrade the Audi R18 E-Tron Quattro (2014) to PR94.

The sooner you unlock a 10 lapper the better, R$ isn't a problem after that :)

Let me know how you get on :)
