I'm thinking of building in one of those Lidl battery chargers in the old
car. So it can be left on float when not in use. The mains lead on those
is only two core and the case plastic. I was considering a Buccaneer
weather proof mains connector mounted in the body below the rear bumper.
Should the car body be connected to mains earth?


No. If the battery charger is double insulated, then the only issue is
preventing the chassis becoming live from a fault on the mains cable.
Cover the mains lead in plastic conduit and ensure that it can't chafe
or snag on anything. Make sure you plug in to an RCD-protected supply.
