It's all down to miles per year, a new car should last 100k miles "without major repairs" and if you drive 10k miles a year (whatever, if it's more it's more in favor of the owner) a car should last at least 10 years.

A new car is $40k, a 10 year old car seems to go for about $10k, so say $3k a year. So with a brand new car, still getting "around" that $6-7k a year.

Or to put it another way - at some point it HAS to be cheaper to own, because someone owns the car that is driving you around!
