Who said anything about software? I’m TALKING about licensing the car, per se. Don’t you think the auto companies would love to contractually prohibit used car sales for the same reason the software companies like to for their product?
Again, it's complicated because automobiles are titled, unlike software. There is an entirely different element of law that deals with real property, and its encumbrances. Licensing isn't one of the allowable encumbrances.
Even still, in answer to your question, probably not. The resale value of a car is a benefit of ownership, an attraction for potential first-time buyers. Mercedes are premium cars, with premium prices, but one benefit is they tend to retain their value better than some other makes. Mercedes actually markets this benefit, and they surely wouldn't want to do anything to complicate it.
Automakers have other less burdensome (to them) ways of adding value - and collecting revenue - from potential resales, and that is with their "certified resale" programs.
Auto makers LIKE used car sales, because people don’t buy extra cars, so they’re either going to run their existing car into the ground (which takes a long time) or sell a car when they’re tired of it (usually much quicker). And once somebody sells their car unless they’re converting to public transportation they’re going to be buying another one.
The reason software companies hate resale is because there’s no hardware. Most software can be run without the CD, and even if the company builds a CD check there’s tons of ways around it. So I can install software and sell the disk to somebody and still use the software. So selling it just means more people using it without paying the company, and it gives me no compelling reason to buy the next version.
