RE: Buying a car and sending it home.
Anything is possible. It depends on how important the car is to you and therefore how much you are willing to spend shipping it home. The first question thats jumps to mind is why on earth would you want to? cars in Chile are not cheap. i'm sure you can find something better in the EU or somewhere at least where you can drive it to Belgium. If the car is that special then you best consult the import/export authorities of Chile www.aduana.ch and if the answer is no from them my suggestion is to drive it to Colombia and ship from there out of the Caribbean.
For an example of the time and cost of buying a car in Chile this is my recount of my purchase a few days ago.
1. Get an RUT document - an identifaction document for non-Chileans. You need a permanent address, thats it. and its free.
2. With the current owner of the car go to the Notorio (the government solicitors office) and get them to create a contract which you and the owner sign then the money is exhanged in front of the solictor and the solictor stanps and certifies the contract. This costs around 50,000 pesos
3. Take the signed and authorised contract to the Registro Civil (Motor Registration Office) and they will do the registration transfer into your name. This costs around 20,000 pesos
4. Go to an insurance office to buy compulsory 3rd party insurance. Really easy, costs around 10-15,000 pesos for a year
5. Hopefully you will have checked the date that the circulation service (road worthy test) is due. If its due while you own it you need to get it done in Chile of course and if all things go well its around 10-15,000 pesos
So all in all you're looking at 100,000 on top of the purchase price.
My car cost 1,300,000 and with all that done i've spent around AU$3,500 which is a fair bit more than what i would be willing pay for this car back home in Australia, or Europe for that matter (its a 1987 Suzuki Samurai). However i made the mistake of searching for a car with free (liberado) registration down south (Patagonia) where the tax free zone is close enough for people to use it to save money on registration costs. However foreigners cannot travel with one of these 'tax free' registered cars.
Hope this helps someone
