Completely anecdotally, almost all of my ongoing car maintenance costs for a 18 year old car I recently sold have been unrelated to the power train. Wheel bearings, steering bushings, brakes. This is probably in part due to the UK annual inspection which checks all these things and forces you to fix them. I agree though that pretty much all the catastrophic scrap-the-car failures are power train related. A lot of modern engines are really, really reliable though, so will happily go for hundreds of thousands of miles without issue.
