Nothing wrong with tri-five Chevy's as I've had a bunch of Nomads,coupes and sedans and enjoyed them. But Buick and Olds came out a year earlier with the interchanging body style for the mid decade 3 year period. They also came out with the 4 door hardtop a year earlier. They may not be lighter than their Chevy brothers, but I've always enjoyed customizing and hot rodding them too. How many others are out there?
