jjsto said:2) As for bringing in a car, I also thought about bringing my family's old 2001 BMW X5. It has about 80k miles and is in great condition. In the states I think it is worth $12-$14k. Here they all seem to be listed over $40k. So, if you bought a used X5 for around $13k in the US, paid $1500 to ship it on a roll-on/roll-off boat, you could have the car here for around $15k. Then after local import taxes your total is about 15 + .8(15) = $27k. (unless they charge more?) So, it seems like, if you pick a high end used car, there might be enough of a difference to justify going through the hassle.
I was told to be careful with this, because at AFIP they don't accept that you buy a 2nd hand car for a "cheap" price abroud. They will tax you on the value that car has here in Argentina, not on the amount you paid for it. So be careful to check that out before doing this.
