Rozakk, as per the status page, there's roughly $6.44 million left which will equate to only about 2,500 EVs - not a whole lot given that the Model S alone will have several hundred takers in Calif. in 2013 not counting the LEAF, the RAV 4 EV etc.
Not too confident that the CARB will add much more if at all. There's not too much to go around in the CA budget.
Btw, the CVRP rebate is literally a check that they cut and send to you in the mail once you apply (right after you get your EV) and after they validate the application. It's different from the Federal tax credit that has to be taken care of in your fed tax return.
