Here are some links to OSI pages. Some of them inspired me in obtaining my car and I am very happy to know some of the persons who maintain websites about their cars. A very special thank you to all of them and I hope too meet you all one day. Some of this links are also in the VINs section.
To the sites owners: If there is something that you want me to correct or include or if you have a site about the OSIs and want me to include it in this section just mail me.
