>Wrong. You're not "throwing away a perfectly good car", you're reselling that car on the used market to someone else You're overestimating the market for cars with >150k miles with lots of quirks that don't bother me (bad speakers, etc). There is a strong chance the car would not sell and would be parted out. The manufacturing of a new car has a large impact on the environment that I'm not sure is offset by the improved efficiency improvement to my relatively little driving (<10k yearly).
