its judt the same as a negative earth one only the other way around, rather than the body being - it would be +

Moder cars are negative earthed because it was found that cars wired positive earth [ground] tend to suffer from chassis and body corrosion more readily than those wired negative earth. The reason is perfectly simple, since metallic corrosion is an electrolytic process where the anode or positive electrode corrodes sacrificially to the cathode. The phenomenon is made use of in the "Cathodic Protection" of steel-hulled ships and underground pipelines where a less 'noble' or more electro-negative metal such as magnesium or aluminum is allowed to corrode sacrificially to the steel thus inhibiting its corrosion

But be careful.

If you have asked this question because you intend to replace any of the electrical system in your car, make sure that what you replace is suitable for use in a Positive earth system
