looking for chevy impala

1. can anyone tell me what was the last year the square/box impala was made.
2. anyone know where i can buy a square/box impala on the east coast of us.
any input would be appreciated

1: 1990
2: autotrader, newspapers, asking around, and looking on street corners for for sale signs and etc

1985 was the last year of the boxy B-Impala. In 1986, it was replaced by a base model Caprice, which was added to the lineup with the existing Caprice Classic. Also, in 1986, an upscale Caprice Classic Brougham was added to the lineup, the first heavy Chevy to feature real hide seats since the 1950s.

The Brougham, especially the 1987-up LS, was essentially Chevy's answer to the Cadillac DeVille.

What was the last year for a two-door coupe?

1987! lol
