Ken, I do hope you manage to get this kit. I found a very good web site, with both the back-story on the amazing prototypes, and great reference pictures. I hope that the site might prove useful. http://www.allcarindex.com/blog/Jiotto-Caspita-FULL-STORY/
Definitely have to agree with what Nacho Z said. Not only is it a great livery, but you knocked it out of the park. I am, however, Porsche biased. All 917s and 956s look outstanding in all their liveries! LOL
Steve and JC, you are both correct about the Tamiya Cobra R. It does not have a full engine. The lower portion is an insert as well as the engine upper portion. You cannot build the engine as a stand alone piece.
Nie, thanks for the comparison of the two kits, and the picture showing the bodies of both side-by-side. They do look to be pretty much the same in terms of proportions. My understanding of a curbside model refers to no engine, chassis or interior detail. These days, most people refer to a car with no engine detail as a curbside.
