I found two more names for the car:
"Beal Stiletto Camaro", designed by Beal Coach Works (owned by Mark Beal, living in California), based on a Camaro Z-28 from around 1983.
"Machiavelli 305 GTS 2+2", produced between 1985 and 1988 by Machiavelli Motors in Key Biscayne, Florida.
Oh, and I cannot resist to quote the original brochure:
"Exquisite taste, said Voltaire, is as rare as exceptional beauty-rarely observable, profoundly elusive, a joy to possess. The designers from I.T.D. proudly introduce a rare blend of exceptional beauty and exquisite taste."
