GM finally put the kabash on the first mini-van that they brought to market after the Caravan craze in 1984, the Chevy Astro and GMC Safari. The two vans barely had an update after 20 years of service. The van's sales had slowed to about 40,000 combined units a year. Since they were designed so long ago each van was a money maker. GM's paid back the initial investment years ago. The Astro/Safari were the last of the rear-wheel drive mini-vans. The Baltimore plant that built the vans will be closed.
