The SL shares the same 3150mm wheelbase, 5255mm length and 1850mm width of the RX it's based on but with its bigger tyres it shares the ST's larger 12.4 metre turning circle. It also sticks with the coil-spring live rear axle common to all Navara dual cab utes.
The interior offers a tasteful mix of piano black, grey vinyl and satin chrome highlights with contrasting white stitching on the dark grey cloth seat trim, which is in stark contrast to the hose-me-out grey vinyl floor. Front occupant comfort is good overall, with a big grab handle on the window pillar making easy entry for the front passenger. However, driver comfort would be improved with some rake adjustment on the driver's seat base cushion.
Large grab handles on both B pillars assist entry for rear-seat passengers. However, for taller adults the low base cushion height relative to the floor results in raised knees and upper thighs, which can become uncomfortable on longer journeys. Rear-seat headroom for tall adults is marginal and there's plenty of shoulder and elbow rubbing if you're carrying three back there. Realistically, like most of today's dual-cab utes, the Navara is a four-seater that can carry five on shorter trips.
Our only major gripe is the warning chime if the driver's door is opened with the key in the ignition - even if the engine has been switched off. Having to remove the key before you open the door each time, just to avoid setting off this chime, is annoying and unnecessary in these days of remote entry.
