I just purchased a 72 Skylark 350 Suncoupe. It has parchment interior with buckets, console, and sport steering wheel with door panels that have imitation wood grain. The 1972 Buick Dealer catalog list the sun roof as an option on all Skylark models. Does that mean that these were not Sun Coupes? It also lists the Sun Coupe as an option on only Skylark 350 Sport Coupes. Were these "Sun Coupes" special cars with manitory options. All Sun Coupes I have seen have had parchment interiors with buckets, console, etc... Were these "Sun Coupe" cars all optioned alike? If there is any one who can answer this riddle, please let me know.
