You forgot the other gems... Monza, Cavalier and Celebrity
Actually the Vega was a cute little wagon or sedan delivery, they had a rotten engine. A small Buick V6 would have made it a much better car. It was essentially the same as a Monza, which was available with a V8. Some Vegas got a SBC transplant.
The rest of those s-boxes...meh. The Celebrity was adequate.
