If you've been keeping count, Buick hasn't offered a manual transmission for one of their cars since 1989. That's almost 22 years. That's also another reason why the brand has been branded as a geriatric cruiser in the past since manual transmission cars are usually preferred by a much younger demographic. The soon to be available Regal GS will have an available 6-speed manual transmission which along with a turbo option should help Buick get on track with their new image direction.
