Do you always recieve the prize car for winning Endurance Races?

[D00msday]

I'm getting close to start being able to do the Endurance Races. So after seeing the unlockables thread, I saw that some of the A-Spec and B-Spec Endurance Races had a pretty good prize car for winning them. (Such as the B-Spec Indy 500) So I am curious to know if you always receive the prize car for winning one of the Endurance Races, because I think it did so in GT4.

Only the first time it is completed do you receive the car.
