The styling of the GX 470's exterior is intended to resemble other Lexus vehicles. Integrated fender flares and illuminated running boards are installed.

The GX 470's wheelbase and length are a bit shorter than the LX 470's. It is slightly taller and 2.4 inches narrower than its costlier companion. A power sunroof is standard. Alloy wheels hold 17-inch tires. Rear Adaptive Height Control raises the vehicle for extra clearance and lowers it for easier entry and exit.
