Ferrari 296 Roadster

The Ferrari 296 GTS marries dramatic mid‑engine styling with razor‑sharp handling and a soundtrack that insists you drive it like you stole it. With the roof down it becomes an intoxicating open‑top thoroughbred that somehow also manages to be surprisingly usable day to day — a gorgeous, grin‑inducing reminder of why people fall for Ferraris.
