did a photoshop pixel count to find my frontal area and the value comes pretty close to the W x H x.81 method, although it turns out the data for my car did not included the width of the mirrors, just the body.

so here it goes:

vectra A (hatchback) 1988 - 1995

width-mirrors (carfolio)
1700mm - 66.9inch

width+mirrors (photoshop calculation)
1945mm - 76.57inch

height (carfolio)
1397mm - 55inch

frontal area (photoshop calculation)
1,92 mē - 20,66sq.ft

0.29 (carfolio .etc)

CdA (calculated)
0,5568 CdA mē - 5,99 CdA sq.ft
