Just a heads up, depending on the model year the supercharged version (RPO L67) required premium fuel (91+octane). And if run hard using regular fuel you can damage the piston tops.
When I was at the 2000 Bonneville media launch in 1999, they referred to it as G-body, related to the Buick Park Avenue and Riviera. I know that there is some confusion about that, as the 1986-99 C, G, K and H platforms were consolidated to the G-body in 2000. It may be labeled as an H but those designations were nothing more than legacies at that point. The cutaway car chassis they showed us was labeled as a G-body. G-body? H-body? You make the call! ;-)
