While also MUCH safer and longer lasting. 'Back in the day' when a car got 100K miles on the odometer, it was pretty much done for. When the family jalopy got up to the mid-to high 60K's it was relegated to 'second car' status. Now, the vast majority of cars last well into a quarter-million mile range without major repairs to drivetrain elements. Airbags, crumple zones, antilock brakes and traction control, back-up cameras, and more nimble handling make newer cars measurably safer for all the occupants.
I take issue with the postulate that newer cars are more expensive to repair. Time was that auto dealers had gigantic repair shops that generated significant sums to the dealership. Now, the showrooms and sales lots seem to take up a far greater percentage of the car dealers' real estate.
