An excellent site for just about any subject under the sun, including car magazines, workshop manuals etc.
Everything is legit and in the public domain and no illegal torrents involved
They have some real oddities such as this old catalog. I just put in "Ford model A" as the search. You can read it on the site or download it in different formats.
If you put "Custom car" in the search and then click the texts only box you get a fair few magazines.
Give it a try
