Thanks for the response your trip is truly inspirational given your minimal travel items and your jeep obviously served you well! Im figuring out how to navigate your web site and have a lot of cool reading ahead. All your documentation is appreciated.
You're very welcome. Please fire away with any questions you have, I really enjoy helping others
Dan, You would be an excellent person to ask the question here - What was the most common brand of vehicle you saw on your journey?
I'm a car guy, and I kept my eye out for cars / brands / models like a hawk. I grew up in Australia, so I'm always intrigued to see what countries have what.
Below I'll focus mostly on 4x4s and "overland" type vehicles, because that's what we're interested in.
As for cars, I would say either Honda Civic or Toyota Corolla were absolutely everywhere, and I mean everywhere.
Most of central America felt like mostly Toyota pickups and older American stuff (Ford, Chevy, GM). Also Mitsubishis, VW Diesel Amarocks.
The exception was the "expensive" CA countries like Costa Rica and Panama which for all intents and purposes looked like the USA does today when it comes to pickups and 4x4s. i.e. dealerships for all the NA brands everywhere. Jeeps common in the expensive countries, not in the poor ones.
South America was an immediate change - Citroens and Renos and other European stuff (that I know next to nothing about). VW Amarock's too (NICE!)
Still lots of older Toyota pickups, and older American stuff. I would say Ford / GM were still around. Mercedes etc were around for big trucks / buses.
Mitsubishi had a presence in the 4x4 scene for sure. Including Patrols, Pajeros, and 4x4 vans too (like Delica)
Poorer countries that needed serious 4x4s went straight for very old Land Cruisers. Old rust buckets with diesels and sold axles.
Every country has very new, nice diesel Toyota Hiluxes too, and new diesel mitsu pickups too.
Jeep was not around in most SA countries until approx. Chile and Argentina, when I would see nice CRD JKs getting around, and Grand Cherokees too.
Interestingly, at one point I went with locals to get parts for their Merc bus in a huge city in Ecuador - we spent and entire day in the "car" district of town, getting prices, going in and out of every shop. I saw every single brand of car I've ever heard of represented in the stores, though I never once saw Jeep (and I was looking). I did find a Jeep dealer in Ecuador.
Same story when I spent days in the car district of Cusco, Peru. (Peru has a Jeep dealer too)
While Toyota pickups seem to be everywhere (especially older ones), I would by no means say I saw Land Cruisers commonly - especially not newer 80s/100s/200s. They were a once a week thing, and Land Rover were not around - other than European Expos. I could count on two hands the number of Defenders (90 or 110) that I saw that were not foreigners.
Luis from Lost World Expedition drove a landcruiser 60, and he says the parts thing is a myth - he hunted for weeks and weeks to get parts for what is supposed to be a common Land Cruiser.
To try to sum it up - I would have to say 80s or 90s Toyota pickups were the most common "4x4" I saw - though I really don't think it matters.
Driving around the world is adventure, and it has hickups and problems. If I was worried about getting parts quickly and easily, I'd never drive more than 10 miles from a NAPA.
Rock Auto.com will ship to any country in the world - so if I was really in a bind I would have ordered something, and spent a couple of weeks hiking or surfing or whatever, then continued on. No big deal at all. Of course, my Jeep never had a single mechanical issue
