But it really didn't make a difference to the longevity of the car. Sure, occasionally a repair was a tad more expensive, but that's it.
The frame, exhaust and suspension generally get corroded and start to fail. You see a lot of 200k Civics and Accords, but few 250k.
You really notice it when traveling to California. Last time I was in SFO with my son, he counted 78 Porsche 911s and about 100 “old” (80s or older) cars on the roads.
