They have all been on sale before, it maybe another year to the next sale, only FM knows. Unless you are a top racer you will need most of your for Le Mans: Legends, to win the car for free, it needs 300~400  for upgrades.

Out of the four cars, IF you have enough for one, I would say buy the TS040 to unlock EK, then farm to buy the R$ Audi R18 in the showcase event. Once the 10 lapper is unlocked R$ is not a problem, still is.
