(It's actually a 2011 Nissan X-Trail, not an X Terra. For some reason the drop-down doesn't give an X-Trail option.)
This one's a beauty. Really comfortable seating, even when carrying 5. I've battle tested it roadtripping across South America, so it's seen ice and snow and rain. Sand and dirt and dusty roads. Dry climates and humid, and it even does pretty well at high altitude. (Don't go nuts on the pedal, obviously.)
Despite all that, it's still at a great mileage and shows no signs of aging. All the systems are running great. We get it checked and cleaned regularly, too. Gets about 500km on a full tank, +/-50km depending on varying conditions and fuels. (The tank is 60-65L, and it takes fuel between 90 and 95 depending on quality in a given country, and altitude.)
I can give you a rundown of any idiosyncracies before you get started, and also happy to give you tips on routes in the region if you're planning on extensive roadtripping. (Crossing borders can be tricky, but we're open to discussing the /permissions needed for that.) ... I don't set a maximum mileage, daily or otherwise. But I'd like to know what you plan to do with the car.
