Also, my tags are due this month; I talked to someone at the Tag Agency and asked about registering the car as electric and she didn't know anything about it. I am a little worried that it might be a long, difficult process and am contemplating just keeping it registered as a gas car. How does everyone else in Oklahoma register their cars?
