Really a BEV would likely be the best option. No fuss and muss. Put a charge point at their place and their car is always charged and ready to go. No oil changes so they won't have to get "scammed". 8 year warranty on the battery for most so that will be covered. But if they are scared of new tech they likely wouldn't go for that. Even something like an older low range Leaf would work for many as they would only need a car for running around town.
