Inside, it’s a high-tech and premium feeling space. The seats are lovely, the tech is big clear and easy to use, the cursed Lexus 'Remote Touch' track pad has been consigned to the history books in favour of a touchscreen and the lovely cabin materials extend to the back tows, too.

This is a pretty straightforward choice, as you get to choose from exactly one engine option. Every GX scores a very punchy 3.5-litre twin-turbo V6 petrol engine, along with a 10-speed automatic that feeds the power to all four wheels.

Only the Overtrail is a five-seater, with the more road-focused trims getting seating for seven.

The big question with seven-seaters is how much room you have in the back, and the GX is pretty generous. I had plenty of room for my 175cm frame behind the driver’s seat, and climbing into the back was relatively easy, too.

The middle-row seats collapse and fold right away, meaning you can climb into the third row without too much grunting. And once there, you’ll find room for adults along with two of the five USB connection points dotted around the cabin.

The entry-level GX nabs 20-inch alloys with a full-size spare, LED lighting all around (including DRLs and fog lights), front and rear scuff plates, roof rails and a powered tailgate hinged at the top, rather than the side.

Inside, there’s synthetic leather trim, heated and ventilated front seats and heated window seats in the second row. There's also three-zone climate, a 14-inch central screen with wireless Apple CarPlay and Android Auto, a 10-speaker stereo, a 12-3-inch driver screen, a head-up display and wireless device charging.

The Sports Luxury is the most expensive GX, at $128,200 before on-roads, and it gets 22-inch wheels, adaptive suspension, better lighting and a fixed glass roof with a sun shade. Inside, there’s a 21-speaker Mark Levinson stereo, leather seats with a massage function for the front row and a digital rear-view mirror, amongst other added goodies.

Then smack-bang in the middle of the GX range is Overtrail, which lists at $122,250, and is designed to be the most off-road-focused model of the lot. It rides on 18-inch alloys, gets special 4WD-focused bumpers and provisional mounts should you want to install rock rails. There’s also an electronic rear diff lock and what Lexus calls a 'Kinetic Dynamic Suspension System', which automatically disconnects the front and rear sway bars for serious wheel articulation when off-roading.

The Lexus GX will clip 100km/h in 7.0secs. Top speed is electronically-limited to 175km/h.

The GX has a big 80-litre fuel tank and the official fuel consumption figure for the combined (urban/extra-urban) cycle is 12.3L/100km. That translates to a theoretical range of 650km. In real-world use consumption's more like 20L/100km which drops the range figure to more like 400km.
