1974/1976/1977 GMC Indy 500 Official Truck
The rise of luxury trucks wasn’t just about wrapping a cab with leather and upgraded features, it was also about special edition trucks. The Indy 500 GMC truck had a body way before they were popular, and the truck rode completely different than your father’s farm truck. The 1977 trucks likely continued the trend of featuring special paint jobs, decals, and badging that celebrated the Indy 500. The Camaro carried on this tradition well into the 1990s for GM (via Motor Trend).
GMC became a premium brand towards the end of the 1990s. But back in the 1970s, this was a new concept for them. The GMC Sierra had a very classic design compared to the Chevy models and it was the perfect truck to be featured in the races. Not to mention the fact that there was a potent power plant under the hood that gave the truck a great deal of performance.
