Every car imaginable has a forum for it, and most have one in English. By classics, do you mean that in a very general sense as in cars from any manufacturer around the world? Or are you mainly interested in American cars of a certain age? For example, if you love Czechoslovakian Tatras, try using "Tatra Forum" as your search term. As they are a popular classic with a unique history, there are plenty of English language sites available. If, on the other hand, you are into something like a ZAZ 968M, you will be limited in what you can find in English (some of which I actually wrote...lol) but you will find plenty in Russian (it was primarily a Soviet Union market car.) However, you can use a translator add on to your browser, or Babelfish to translate from multiple different languages into English. Some languages translate better into English than others. Japanese, for example, uses a different syntax structure and therefore it will not always make sense out of a translator. I also learn a lot from blog sites like "Bring a Trailer" or "EnglishRussia", to name a few. I use these sites to learn the names of cars I had never heard of before, and then I start researching them until I have added to my mental data base of useless knowledge.
