Patrick, I used to have a long commute, so I put plenty of miles on cars in rush hour traffic. I had one Datsun pickup truck that lasted a long time, until the floor boards rusted through (you could see the road go by), the carburetor gave out and the paint all peeled off. I gave it away to a guy who completely rebuilt it, repaired it and then sold it to raise money to support his family. The pictures of it when he got done almost got me to buy it back! And yes, a well-maintained car will run a long time these days, and the three you mentioned (two Nissans and a Suzuki) are all three made by the Japanese, who do make vehicles to last, unlike Detroit. I now drive mostly Toyotas, and have had some of them go a long time (up to 6 years before I gave them to my children). They then drove them longer, in some cases up to a total of about 15 years. But they always need "upgrading" of brakes, shocks, drive train, etc, etc, to keep going.
My computers I mentioned just have the operating system updated as far as it will go. One had an HD fail, so I replaced it with a SSD, but other than that, they do what they were designed to do with no other intervention from me. Both run 24/7/365, rarely get rebooted (usually just for some software update). The backup laptop had the mobo replaced by Apple under the GPU program a while ago, and they put a new battery in at the same time, but it just sits there, waiting in the bullpen to be called into service when one of the others quits. But they keep saying, "not yet, rookie!"
