Yes I was referring to new (or near new) cars.
Your personal experience of a used car increasing in value demonstrates a shortage of used vehicles. For serious uptake there needs to be new EVs purchased in significant quantities, which means they need to be cheaper.
New EV's are much more expensive in NZ compared to other countries due to the lack of subsidies here, unlike Japan, the US, Europe etc. where there are significant rebates for purchasing a new EV.
A subsidy doesn't change the cost, just who pays it.
Manufacturers should simply be producing EVs cheaper.
If you think about EVs from a technology rather than automotive perspective, the constrained supply and high prices are a familiar tactic.
