You will need to first obtain a smog check from a smog station in California. Once the vehicle passes the smog test (and it should, if the check engine light is not on, the vehicle's emissions system is functioning properly and has not been tampered with, and its emission monitors are complete), the smog test results and certificate number will be electronically transmitted to the DMV. The new owner can then register the vehicle in his or her name; upon showing proof of California auto insurance. You will need to hand over the vehicle's title (pink slip) to the new owner and they will need to present the title to the DMV, along with a bill of sale, indicating the date of sale and purchase price.
