Has to meet both emissions and safety standards (but those are probably correct or close to it on a new Tesla).  You also have to pay customs duties of 2.5% on cars.  And shipping.  Not a super cheap or quick process.  That's close to $4000 in duty and shipping per my back of napkin calcs.  But it might possibly save some money in the right circumstances.

You know I was kidding about the emissions, but the rest is cool :-)
