Buying a GTO but noticed all the clones out there

Look for subtle differences between a documented GTO and one you are considering purchasing. Location of badges, minor trim pieces like the grab bar for the passenger's seat (only on GTO), owner history documents, clean title, tail lights, and the like. Make it a point to attend local car shows and take pictures of displayed cars (to assess for consistency with what you think is a true GTO). It may take time but in the end it is worth it for the money real GTO's bring. Also join a users forum. They are a good source of info. Good luck.

Don't buy one without PHS documentation. The 1964 GTO's are very difficult to verify no matter how much information you have.
