Saturn Plans 80 New Dealerships: Saturn Corp. plans to open 80 new dealerships over the next year, and its assembly plant will start round-the-clock production in January to supply them. Company spokeswoman Nanette Wiatr said General Motors Corp. had planned the expansion long before Saturn sales took off and some dealers sold more than twice their expected volume. “We’ve wanted to do this for a long time,” she said. Saturn now has 221 outlets in 43 states.
