Positioned between the RX 300 crossover and LX 470, the new GX 470 is a four-wheel drive equipped luxury vehicle based on the Toyota 4Runner frame. The 2003 Lexus GX 470 is richly-equipped with standard 17-inch wheels and side curtain airbags. A Downhill Assist Control and Hill-Start Assist Control technology incorporated on the Lexus GX 470 allow it to be as effective off-road as it is on-road. A new five-speed automatic transmission handles power from the 4.7-liter V-8 engine of the 2003 Lexus LX 470 luxury utility vehicle. Standard side airbags and an optional night vision system also stand out as updates to the full-sized luxury utility product. Larger 17-inch wheels are found on the 2003 LS 430 while the SC 430 convertible gains optional subscription-based Lexus Link safety and security system.
