Overall width: 72.3 inches
Overall height: 43.7 inches

72.3 x 43.7 = 3160 x .84 = 2654 / 144 = 18.4 sq ft estimated frontal area. The greenhouse angles in more than most but then the tires might be fatter than most so who knows which way the formula should be adjusted.

Another web source places it at 18.6 sq ft but that's just another estimate.

Various web sources give Cd at .27, .28, and .32; for the .27 and .28 it was not stated if those were estimates or figures given by GM. The .32 was estimated.

It's a beauty and I sure would like to have it in my driveway, especially since it has one of my favorite engines, the 3800 V6.
