Are they still doing appointments (cant seem to find it on web site and calling) or do/can I do a walk in for a : change of address, change a title in my name for a new vehicle, and vehicles registration updates?

I just walked in. I applied for a RealID and was in and out in an hour on a Friday afternoon, even with all the people there. Just prepare as much paperwork online as possible before going to streamline the process.

Yes to appointments but seriously I wonder if it even makes a difference at the Temecula office. In all fairness I applaud the efficiency and people who work there, even with Covid conditions in affect, they push a seemingly ridiculous line through quicker than you might expect.

Yup

Yes
