I can foresee a whole new legal market opening up - that of lawsuits from people who buy wrecked cars from the U.S. and then sue the previous owner, the junkyard the insurance company and the guy who does the buying and shipping when the cars explode or the brakes fail or the radio causes deafness or whatever. You just know that if members of our litiginous society were engaging in such a practice, such lawsuits would be shot around left and right.
Apparently, at least for the time being, these Central Americans are happy with their totaled BMW's and Mercedes. Just wait till these rebuilt vehicles fall apart in some Nicaraguan jungle and the driver gets post-traumatic stress from being ambushed by cocaine smugglers. All because the jury-rigged vehicle he was in didn't come with a warning label: "Caution! This previously wrecked vehicle may cause death, mayhem and destruction of you, your family and assorted bystanders on the sidewalk. Rebuild at your own risk."
