We are from Europe, 4 years ago for our honeymoon trip we bought a motorbike in Colombia and drove it to Buenos Aires.
This year I am planning to fly to Panama at the end of November/ beginning of December with my wife and our baby, buy there a car and drive it to Mexico or the USA. (We are about to buy an airplane ticket, so generally we could do it in the other direction too).
We want to have freedom of stoping on the way where we want. It does not have to be a car we could sleep in. Any reasonable offers accepted.
