Having been an expat, one option is do you really need a vehicle? And when you do what about renting? Does your employer supply you with a vehicle??Have you been to Guyana yet? When I lived there for a while I drove a 2004 Hilux and loved it, RHD manual and all. Can you buy something used locally? I don’t think I would take a Tacoma there, I don’t know how much dealer support you would have. I don’t recall seeing many 200 series there either, it was mostly 70 series land cruisers
Don’t forget it’s a RHD country. It was weird enough to learn to drive on the “wrong” side of the road in a car properly set up for it. LHD in a RHD world would add some complexity
Given the RHD bit is reason enough that I would look locally. Even if more expensive, there is much to be said about blending in with locals.
