They weighed almost 800 lbs more than a Malibu.
Just jerking your chain. They were a no frills performance car. No carpet or trim, but you could get one with a big block, 4 speed and 12 bolt. Kinda like back in the 60's when you could get a Biscayne with the most powerful drivetrain available at the time, on steel wheels with hub caps. The ultimate sleepers.
