Yo Mike,
As long as the car was manufactured as 50 state legal and could be sold in california new then you can bring it in as long as you pay a "use tax" which is not a big deal. Furthermore, Saleen is classified as a manufacturer and was manufactured in California so everything else is moot. And it's 7,500 miles and under is considered new.
All I needed to register my S351 here when I bought it years ago was my Saleen CATALYST sticker right where it should be under the hood. I had to declare it because it only had 4,000 miles on it when I bought it.
