Welcome:-)
The forum overall is pretty quiet, there are a lot of members but no everyday activity. There still is however, a group of longtime members which still "lurk" in the background and post from time to time.
I am a big fan of old American cars as well, you can find a lot of pictures in the media section called "Matt's HiRes Hide-Out". And you could check out the UCP main page with tons of information and photo's from cars and events.
This is a nice place, enjoy!
Regards,
Erik
