Funny, as a Gen X-er I was reading this as a story about somebody else, but you're totally right. I'm 41 and I've only ever owned one new car. We bought it when my wife was pregnant, because I wanted to make sure she had a good reliable car for her 30-minute commute to and from work. That car has lasted five years so far, and fate willing it will last at least another five. (Her commute is only five minutes these days, and the carseat is in our purchased-used minivan.)

It's really a crazy contrast from what I remember a number of adults doing back in the 80s -- a new car every two years, regular as clockwork.
