And that is largely offset by how long modern vehicles last.This ignores the fact that mandates over the last 70 years have dramatically affected the price of vehicles. The Governments hand lays heavy on the auto industry, we are getting the vehicles that many people voted for.
I look at a vehicle as a commodity that I am buying by the mile. For someone with some skills buying used can be the cheaper route. For someone with no aptitude or skills it will require paying someone else to perform repairs and maintenance. There are times when the fixed cost of a lease is cheaper, not for everyone though. Its all about being an informed consumer and playing the long game.
Yes, they have more features and cost more. Yet, you can take most to 200k miles compared to the struggle of getting a vehicle from 50 years ago to 100k.
As you mention, cost / mile. The costs are the same or lower when you look at the modern lifecycle.
