I recently came across an interesting question on a forum for the Mazda6: at which point did your car stop feeling new?

More pointedly: when does a car start feeling old, and what change makes it feel that way?

Repairs are one thing. But what many people really want to avoid is the feeling that they’re driving a piece of junk. What leads to this feeling with a car? How does it vary by age and source for different car models?

If we can nail the answers to these questions down–which won’t be easy–this might be a statistic we can compile and track by car model and model year.

So, anyone have thoughts or suggestions?
