Escalades and other expensive rides are worth the trouble to containerize and export. But the more of any particular make/model on the road the more are stolen. Partly because there are more targets of opportunity but mostly there is a bigger demand for repair parts. The mechanicals are always available at the junk yard or Pep Boys but body and trim parts are always at a premium. If a car costs $30K then to buy that car in new parts would be at least $170K and assembly is extra.
I remember a couple years ago reading about a guy that had a brand new car stolen. The car was recovered in perfect condition except the seats and seat belts were missing. Since this was a new model from Toyota and replacement seats were not available, the insurance company totaled the $ 20odd K car.
It seems stupid until you realize the Ins co will part out that car and at least break even.
