We're more than happy to share but you'd need to be a bit more specific with your questions. In a nutshell we spent an average of $96.64 per day over the 559 days we drove S.A ($54,022.94). That includes shipping from Panama to Colombia, shipping the rig back to the US from Uruguay, all of our flights, and a posh 2 week Galapagos cruise. We blogged about most of our trip but we abruptly stopped blogging when we entered Chile so the final 3 countries are incomplete. IIRC, on another thread you mentioned that your plan is for 6 months so our itinerary probably isn't helpful since we spent 3 times that. We drove south then north to Uruguay, we didn't yoyo the continent. With such a short timeline it would be better to ship in and out from different countries.
