Problem I see w/ the poll is it is undefined as in what defines "Best"?
From a performance only standpoint it is the GNX as the only possible answer, followed closely by GN and every cold air Turbo Regal.
From a styling only standpoint it would be the Hurst Olds followed by 82 Designer series Turbo Regal then 84 GN
Beyond that it falls to personal preference, because what one person likes about a car someone else will equally hate with every opinion in between.
