pontiac_firebird_web.jpgDETROIT (AP) _ The Pontiac name plate is is going out of business.

The General Motors brand was known for muscle cars drag-raced down boulevards, parked at drive-ins and roared across movie screens.

The 84-year-old brand has been moribund since GM decided to kill it last year as it collapsed into bankruptcy and was in decline for years before that.

It was undone by a combination of poor corporate strategy and changing driver tastes.

GM's agreements with Pontiac dealers expire Sunday.

Pontiac's sales peaked at about 1 million in 1968, when the brand's speedier models were prized for their powerful engines and scowling grills.
