Either of these are fine, we're not very likely to be followed by reporters, and if we are switching cars will probably throw them off. The point of the original plan was that to an observer from Manticore we look like just another person driving down this street, with nothing to indicate that we're looking for the Scavengers or merit any closer investigation. Dodgy illusions or fake or obscured licence plates potentially break that. Just driving a regular, legal car in a regular, legal way, does not. If we need to make a closer approach we can park the car somewhere else and walk back.
