LIVONIA, MI – General Motors Corp. should pay more attention to Chevrolet, its flagship division, says Michael Jackson, CEO of AutoNation Inc., the country’s largest dealership chain.

He’s baffled that GM has tried to bolster weaker brands, such as Buick and Saturn, by giving them preferential treatment with new-product infusions – at the expense of Chevrolet.

“You don’t neglect your strongest brand like that,” Jackson says on the TV show “Autoline Detroit with John McElroy.”

Chevrolet should get all new products first, he says, emphasizing that other brands should ultimately get their own derivations.

“Being the oldest child has its privileges,” Jackson says of Chevrolet, although, technically, Buick, founded in 1901, is 10 years older than Chevy.

AutoNation has more Chevrolet franchises than any other GM brand, Jackson acknowledges.
