Someone should inform the Wall Street Journal they cited a very biased (probably fake) hedge fund manager, who spends his entire day ranting about Tesla on Twitter and talking with himself via another Twitter account , as an authority for an article. Tesla to Upgrade Slower-Selling Version of Model S - WSJ The 70D will likey sell very well. I'd be willing to bet Tesla is going to offer anyone who owns a 60kwh Model S to upgrade to the 70D. The 70D will be very relevant when Tesla begins to promote the CPO program. The 60KwH Model S will likely be $35,000 $45,000 after 3 years, and will depreciate at a very slow rate, because of the warranty.
