I've been planning on buying a NETA V due to low prices, too.
However, the company producing the NETA V recently cut 400 jobs in Thailand and has severe financial problems.
So I'm a bit worried about future availability of spare parts for NETA cars.
I also do worry about the mentioned crash safety rating. Otherwise, I think a modern EV is a good choice, and will be less trouble than an ICE car, for a long time. LFP batteries will most likely outlast the car itself (note that 2023 Neta V have been produced with LFP and NMC batteries). Also, LFP batteries are significantly safer than NMC batteries.
