All of the technical advances with electronics are great. However, when a car is on its 4th or 5th owner, the price point of the car is probably very affordable. But, the cost to repair/replace the high tech stuff like adaptive cruise control or collision avoidance sensors will most likely remain expensive. I imagine some person happy to buy a aging great car for a reasonable amount, and that equipment quits working, many owners will choose not to fix it. And like Hellrat posted, many of the modules may not be available to replace.
