When Tesla put an end to free lifetime Supercharger access for new customers, it left more than a few people crestfallen -- one of the nicer perks of ownership just went out the window. However, Tesla has had a (partial) change of heart. As of now, any existing owner has free Supercharger use, even if you bought after the January 15th cut-off. And if you upgrade to a Model S or Model X in the future, you'll get to keep that gratis electricity. There aren't many people who'll need the offer right away (the Model S is only 5 years old), but this could give you a reason to upgrade quickly instead of holding on to your EV for as long as possible. And if you're a first-time buyer, don't fret -- you'll have a way of scoring free charging as well.
