Used Hyundai IONIQ (2018) owner here. Buying is difficult, because most sellers know little about electric cars.
I recommend buying cars that come directly from a leasing contract.
Those cars often have low mileage, were serviced regularly and early problems fixed via warranty. Demand and prices for used cars are low because newer EVs have higher mileage in comparison.
Take a OBD dongle with you and read the battery SOH.
Also Check the Manufacturer warranty terms before buying.
All in all - buying a used EV was (longterm) the least expensive option for me and also less risky.
Electronic Systems tend to have more problems early on and way less, once they are “stable”.
I recommend.
(But Teslas are a whole chapter for themselves. I heard horror stories with their proprietary systems and app-based-services. Maybe someone else can elaborate)
I just rearranged the Episodes so that they match the word order from yoda (for OCD reasons).
