how to unlock the one-make races?

[redl1nerpm]

So Ive beat everything (all S,A,B,C and available one-makes) with a bronze or better that I can possibly beat, but theres several one-makes that never unlocked (i.e. the NSX, Mustang etc.). I did a search but didn't come up with anything. How did you guys get these one-makes? All golds or something?

A search for the term "unlock" in the GT5 Prologue forum found this thread.
