Agreed... she's gone so many times farther than anything was ever engineered for service life. Not picking on the car at all, but she's prime laboratory study material due to the mileage.
The aviation guys seem to be most familiar with this idea... fun to think about next time your staring out the airplane window at that flexing/flapping wing, that eventually it will be replaced due to metal fatigue and those guys have an inspection schedule to check for cracks on the rest of the skin/framework... I still don't feel warm and fuzzy about the 787 construction (glue/plastic... not to mention the lithium batteries). Had an engineer customer back in the 80's who wouldn't own a car from that era with more than 60k on the odometer, just because of metal fatigue. I had the conversation several times with him... I just couldn't wrap my head around it. Most of the cars I've owned started at over 100k and a few had far more than that.
