stenkb, you have every right to be angry with Tesla for their handling of this situation. Even if their policy is to not do trade-ins, they should responsibly communicate with you. There is no justification for this, judging by the facts as described in this thread. Leaving you hanging in the wind with no explanation and no plan on what to do with your Roadster or your Model S is inexcusable, disrespectful, and far from how Tesla Motors wants to be perceived.
I suspect that they decided after trading in Steve's car that they may have changed their policies on trade-ins, but that is secondary to the bigger issue of horrible communications and updates. You just can't treat people that way, and definitely not people who spend hundreds of thousands of dollars on their cars.
