"Nothing can go wrong with them" is actually a pretty good pitch to go for a 2nd hand long range EV. My issue with buying a new EV in NZ at the moment is the pace at which next gen battery tech (more range, faster charging) is being introduced to existing models in China which will find its way here. Most new PHEV's pretty much use the gas motor as generator for the battery, yes higher maintenance costs but also cheaper upfront prices. PHEV's will take care of most daily commutes on pure EV, you can granny charge back up to 100% each night, and you have the advantage of reduced range anxiety/needing to spend 20+ minutes at a charging station if you do long weekend trips. Tough call though.
You should have a look at how well the older Mitsubishi Outlander PHEV's are doing. Especially the older version with only 13.8kWh battery.
Most PHEV's have small batteries, which means that when you have some degradation of the battery you will go from being able to use it on battery all the time, to only being able to use the battery from time to time. And when that happens you are lugging around a battery that is actually causing you to use more petrol than a regular hybrid version of the same car would use.
Charging to 100% each day on a NMC battery is also going to make sure you degrade the battery quicker than if you could keep it within 80% charge most of the time.
I have also seen mention of the Outlander running on the petrol engine when you start driving if the temperature is under 10C.
My opinion is that PHEVs are in the market mostly to cater to people believing in the myth of the limited range of EVs, the strange perception that you need 1000KM of range, and for the car manufacturers to get their on paper CO2 emissions down.
