27: 1974 Pontiac Ventura GTO
The original Pontiac GTO gets a lot of glory in the muscle car world but there were also other GTO models. The 1974 Pontiac Ventura GTO was released at a strange time for the brand because it was a smaller version of the original GTO that the company had sold (via Hagerty).
Performance-wise, this variation of the GTO didn’t break any records but it could hold its own. As automakers worked toward downsizing their lineups, this was a more economical version of the GTO. Unfortunately, it never sold well, and this is one of the lesser-known GTO models.
