“Standard cars in this day and age are expected to keep running up to 200,000 miles, while cars with electric engines are expected to last for up to 300,000 miles.” https://www.caranddriver.com/research/a32758625/how-many-mil...

Of note older cars tend to go to be driven by teens etc who drive less meaning EV range is less of a concern. Meanwhile battery replacement costs keep falling, 13k to replace a model 3’s battery is way down and predicted to falling further. So the used market is likely to segregate with some % seeing 1 battery replacement in their lifetime and others having quite significant degradation.
