I did some checking on the Chevy Impala, here's what I found out. The Impala has been built by Chevy during these years: 1958–1985 1994–1996 2000–present It's built in Arlington, Texas ... about 2 miles from where I am sitting right now. It took over the Chevy Lumina spot, so in fact sales for both vehicles have been folded into this model since 2000. 2006 - 6th Generation The 2006 Impala is essentially the sixth generation of Impala. It's on the GM W platform. It really does have more of a family sedan look and a lot of long-time Impala fans wanted a more agressive look. Nonetheless, it's selling.
