no, my car does not do perpetual motion, can't trying someday I guess though.
as far permanent/rare earth magnets, any magnet that does derive its magnetic field from an electrical current is permanent, this means that refridgerator (ceramic) alcon(spelling?) ferrous, and even the super duper NIB (neodynanim iron boron alloy ground up and pressed together under high heat) all can be permanent magnets. they can all also lose their magnetic fields. its all about the alignment of the particles in the material. and no, the magnetic fields even with the NIB magnets are not particularly strong when compared to a chemical reaction's ability to cause movement. but a whole bunch of them constantly creating their small amount of power could make something worth using at the appropriate scale. so in theory its very possible to use these natural forces to create power, in practice there have been a few people that seem to have done it, but not many people have replicated their results or made a unit with enough energy density to use for an automobile.
youtube up parendev motor or howard johnson magnet motor and you can see some that appear to work well, the hojo model even running an alternator at pretty high speed.
