Really that 1 of 6 means nothing in the big scheme of things.
That's just something guys like to say to make something sound even more rare.
Saleens came so many different ways, damn near anything could change the ratio.
My explorer would probably be 1 of 1, based on options for 2000
Or 1 of 31 Based on options and year
Or 1 of 120 based on total number of truck in 3 years
But i just say 1 of 120 because that's how many were made total.
Now if that saleen were to of had an SC on it from the factory (which didn't come till later) that would be worth mentioning.
That car is hurting, missing important things, like rear valence, rims, i'm sure the seats are torn up.
Worth saving? absolutely, a cost effective project for a young mustang noob, probably not.
All the info is readily available in the saleen book, give me the number of the car and i'll look it up.
