They earn their weight in hugely reduced pollution, even if they may cause a few gallons more fuel over the life of the car. At least there's a trade-off that's really worth it.
Keeping light old clunkers going may get good mpg and be good for your wallet, but unfortunately it's not quite so good for the environment.

Electric everything and almost trying to make a car interior into a sound studio is a real heavyweight mpg-killer.
If car manufacturers kept out most of the
creature comfort options, they could build simple but cleaner cars for a lot less $$$, so less wealthy people who now keep old bangers going could get a chance to buy a far less polluting and safer car.
That's what Renault is doing with its revived Dacia brand.
