I bought the AeroVironment charger from the dealership (it is probably the one the dealer uses). I called to schedule installation, give them payment information, fill out a questionnaire (where is the charger going, can your home electrical support the installation, etc.). I think I'm ready to go then they send me a contract to sign. They already contacted the local electrician, who sent me an e-mail. I know a lot of people don't read those but I do, and among other things it basically disclaimed any warranty, required to to file legal claims in California (I live on the East Coast, the flight alone would cost as much as the charger). So I cancelled the install, and now I have to fight them to take the charger back. Long story short - don't buy the AeroVironment charger. Checking the other threads for recommendations.
