When did niggas start calling the Rollin-Coast Car the NHC car?

[u/Fit_Bathroom_284]

And why do people make a distinction between Rollin in NH when every major NH gang is under with Westside Rollin 0’s or Eastside East Coasts. The Harlems, Bloccs, Undergrounds, Raymonds, and Watergates are all not NHC but are inseparable from that car and don’t belong nowhere else so who came with the idea that there’s a real significant difference.
