Not everybody considers things like cars as throw-a-way. His car, by description is not anywhere near run out.
Before buying my Leaf, my daily car was 23 years old, I still have it.
My next newest vehicle is 40 years old, and I just put a used transmission and a new timing chain plus rod bearings in it.
Both will give many more years of service. My oldest is 83 years old and can still move a load. (truck)
I bought the Leaf not because it was a good "investment", vehicle are a bad investment, always loosing value. I bought so I could fuel at home, try the new electrics and learn about them, and also give my wife the newer and more safe tech found on cars not 24 years old. The car it replaced didn't have ABS, and after 24 years I have no faith in the air bags.
The 40 year old car has no ABS or air bags.
A Green-tec used battery or a LRN new battery, the old cells are turned in and used for less demanding electrical storage.
Those that trade off aren't reducing their carbon foot print, those that hold or buy used and hold are.
There is a lot to be said for holding on to something that you know the history and what it needs rather than throwing out and buying new or used where you don't know the history and/or condition.
A car is rarely purchased on the economics alone, although few would be willing to admit it.
Cars that I have got rid of, mostly because of rust, or a major flaw that is difficult to over come. I had one that cracked heads, every 100,000 mi or so and the only permanent fix would be a re-designed head being cast. That and the rust problem sent it down the road. I loved the ride and comfort, but it was not fixable for the long term.
I know I am in the minority, otherwise the LRN would be doing a booming business. If not directly from retail customers or by purchasing the used trades and reconditioning.
