Puerto Rico is an island in the Caribbean, which means that it will have to be sent via ship; most ocean-going car carriers are roll-on, roll-off ships (ROROs in shipping lingo) that are essentially floating parking ramps. That means that there will typically be three pairs of loadings and unloadings rather than one set; from home to car hauler, from car hauler to ship, from ship to Puerto Rican car hauler and then on to the new locale. That means that there is three times where glitches loading and unloading can happen, not to mention any problems that might crop up on the RORO voyage.
