The sleek, polished dark blue 1978 Cadillac Seville eased slowly out of a showroom near Iran's capital, its driver carefully inserting the 8-track tape that came with it to blast the sounds of a time long since past.
The Sevilles, once assembled in Iran, represented the height of luxury in the country just before the 1979 Islamic Revolution. General Motors had partnered with an Iranian firm to build the sedans, selling them for two-and-a-half times the price in America at the zenith of the country's oil wealth.
