The 'A' simply means that the interior items other than the seats are black. The 'B' is for blue, 'S' for sandalwood, 'G' for green, etc...
If there is a single digit after the 'A', that would indicate the # of exterior moldings. This number can be blank for zero, or 1-3 but never a 4. We don't believe that Chevy produced Novas with all 4 ext. moldings.
We all love self-professed experts, especially in the Nova world
Obviously the majority of the non-SS Novas were bench seat economy cars. However, there is a fair percentage of SS cars that were nicely optioned. Not everyone raced after a Camaro, Chevelle or Corvette - some people preferred the looks of the Nova, and were willing to pay up for a fancy one. One editor coined the phrase 'a Camaro is nothing more than a gussied up Nova', so it's all in the perspective I guess!! I wish Tony would ask some more, that was an enjoyable read
