Sadly, people are not rational, and will buy the new car because it makes them feel good. They'll give them a year of free features and people will forget all about it because it's a free year and "a $5,000 value!"
I've only ever bought one new car, and that got dieselgated. I will never buy a new car again, and you won't, but there's not enough of us to stop this from happening.
