I've been on that page for quite sometime now, and Scott Giesenhagen and the rest do a phenomenal job of finding these 70's era pics and cars that are amazing. I'm probably on that page more than any other page on FB.
For other fans of 70's street machines, the page of the same name on Tumbler is also fantastic and will really take you back:
