I like it too...very cool!!! .
The louvre vents in the deck would indicate a '71...like some other GM products had that year. .
Although not as popular, I always thought the notchbacks were cooler than the fastbacks...kind've a base car thing. .
Thinking about it now, were all the well known Drag cars a fastback or any notchbacks of fame?? .
Back in the day they were everywhere here in Canada...Astres too! . They didn't do well here in the rust belt and I haven't seen one in a long time either? .
