Please find me original owner, mint, low mileage ZXs for around $4600 and I will gladly buy each and every one of them.
But, this indicate the situation you (and all other potential auto investors) are in: your car has only a couple of things separating it from any other Z car in a similar state of condition, and which like any other car has established values.
Getting someone to pony up $ from even the price estimates given here (from $7K up to a mentioned $30K) means your car has to be from $3K t0 $27K more special than any other vert on the market in relatively similar state in order to earn that extra $. Here in Washington State verts and Z32's are not uncommon at all and for sale all the time, and I've seen several in the condition you claim- they ALL sell closer to that KBB value than the loftier prices people will throw out there, or they sit for months and months and months without sale.
So really your best bet is to keep her and enjoy her lightly and be sure ALL maintenance is done, which surely has not been the case, and hope someone sees it along the way and is pushed to offer you a decent price above the values that all of the others must abide by.
