Full 1999 GMC Sonoma Review
What's New for 1999
The '99 Sonoma touts four new exterior colors, a new steering wheel with mini-module depowered airbag and larger, more robust outside rearview mirrors, with the uplevel power mirror gaining a heated feature. AutoTrac, GM's electronic push-button two-speed transfer case, is now standard on four-wheel-drive models, and all Sonomas get a content theft alarm with remote keyless entry as well as a flash-to-pass headlamp feature for the smart stalk. Serious four-wheelers can now order composite skid plates.
