Where is Buick made?

Every 1995-1999 Riviera was produced in the same GM plant in Orion, MI. GM produced less than 90,000 of these cars beginning in May of 1994. Almost half of them, 43,000, were 1995 models. The last 200 Rivieras were the coveted, numbered Silver Arrow version, the epitome of this styles creation. After production ceased in 1998 (the '99s are retagged '98 inventory) GM closed and disassembled the Orion plant. They were destined to be a collectors item.
