This is always a great place to start. There are as you may have seen already places on line that always link back to the Tesla CPO vehicles. What I would recommend is to contact the person below and get on the inside of Tesla. These are people that know about CPO's and other vehicles that have not hit the market yet. Best of luck, and always compare your odds with new and take advantage of the FED Tax of $7,500.00 while it last this year.
