To give you a little perspective on how long an automobile should last. My business owns a fleet of approx. (15) Ford F-150 and F-250 pickups. They are well maintained, serviced and cleaned regularly, and run down the highway week in and week out in all types of weather including snow, slush, salt, etc. loaded with men and tools. Most go to an employees home each night / weekend and sit outdoors, rarely garaged.
We typically get about 250,000 miles or ten years out of these vehicles. Routine maintenance and repair items include; oil changes, tires, wipers, radiator and transmission flush, brakes, etc. Major repairs such as transmission, engine, etc. are rare.
After all of this use, they still look pretty good and we sell them for $3-4000 when we are done with them.
Modern vehicles will last a long time if well cared for.
