If you check out a lot of used-car sites right now, you’ll see that a 2016 Navara ST-X can cost anywhere from $10,000 to $55,000. Why the huge price-range? Because there are so many variables with this type of vehicle. Frankly, I’d need a lot more information to make any sort of educated guess on the value of a car I haven’t even seen, so I’m not going to offer one.

Because this type of vehicle is often used off-road, its condition is crucial. If it’s been bashed up, you can take thousands off the price. Has it been a hard working tradie truck, towing a huge trailer every day? How’s the service record? What distance has it covered? What accessories are fitted? What’s its overall condition? Has it been heavily modified (A lot of Navara four-wheel-drives have)? Is it a dual-cab, single-cab? Is it fitted with a tub, a canopy or a drop-side tray?

Without all this information, it’s simply impossible to hazard a guess at the vehicle’s value.

It’s at the high end of the range, but it seems fair.

Unless it’s a massive leak that drains the oil from the engine, which is most unlikely, it won’t affect the engine.
