Yes, I'm looking with that slant in mind.
Pretty much the same could be said for European cars as well, and I'd venture to guess most German or Italian makes have manuals available in English as well. Of course I could be wrong there, but I'd guess with Great Britain right next door, the manufacturers would supply service manuals in multiple languages.

What other cars would you expect to see in the class aside from US, Japanese, and European makes? I'm not expecting to see anything Russian or Arabic or Piglatin show up to race since those cars weren't available for sale in the US and thus violate rule #1.
