There are few 12-cylinder cars left on sale, as many have been replaced by V8 hybrid alternatives. However, there are a few that are worth considering.

Both Aston Martin and Lamborghini could launch convertible versions of their V12 supercars - the Vanquish and Revuelto, respectively - in 2026. You can inquire or even put in an inquiry with their dealerships, but even if so, your delivery will unlikely happen before 2027. 

However, the better option is the Ferrari 12Cilindri, which is already on sale in India. Unlike the aforementioned two models, the 12Cilindri is pure naturally aspirated V12, without a turbocharger or hybrid assistance, and will likely be a future collector's item. 

The engine sounds exceptional, and performance is strong and fluid. The car itself is exceptionally engineered, with the latest F1-derived electronic assistance.
