Colombia SOAT Insurance for a 1 month term
Julia, thanks for the tip, I just purchased a one month SOAT policy from Previsora today, and it was incredibly easy. It was 30,000 pesos (or about $17 USD). Their contact info is:
Calle 57 # 9-07
(57 1) 348 5757
I would call them if at all possible prior to arriving to make sure you can get the policy you're looking for.
If you are already in Bogota, I would strongly recommend taking a taxi to this place as it is a bit difficult to find if you're not used to driving in the city.
To clarify, SOAT is the bare minimum insurance to keep you legal. There are also supplementary policies that you can purchase, but most HUBBers do not elect to get extra coverage (in fact, a good portion seem to prefer driving without any insurance at all).
