This body style ran from 1973-75, and the grill on the model is vague enough it could be any of them. The C pillar on most '75s is different, but a quick look showed me the SS variant retained the C pillar from the previous years and the grill seems to me closer to the model. I could be mistaken.

I don't recall Johnny Lightning ever getting around to this model car, I know they covered the Olds Cutlass ('76-77), and I don't recall ever seeing one done by M2 or Greenlight. That would leave this as the only representative of this car in small scale, at least that I know of. A product of its time, it could be a lot better, and the size is a good bit closer to HO than 1/64, somewhere in the middle I would guess around 1/72. It does have opening doors going for it, and the wheels are HW blackwall-esque, meaning they at least look presentable.

These old Chevelles were very common on the road back in the day and popular with the High School crowd, not so much anymore. Smogged and detuned, in other words "gutless," it would be hard to call them a muscle car but against their contemporaries they did OK. Huge by today's standards they were mid-size back then.

I wasn't into diecast at the time this car was on the roads, so I don't know for certain when this Zylmex casting was first issued, but by the construction I would guess it was not too many years after the car was new.
