You should try one of the new SRT8s ... bumped up the HP by 15 to 485. I rented every one I could before buying mine. I found the SXTs (V6) to be a bit peppier than the 5.7L V8s (R/Ts). Then there's the Hellcat of course.
I enjoy both the Boxster and the Challenger as drivers, for very different driving experiences. I will be getting another Boxster as a driver (newer) once the 986 gets converted to Spec (should happen this winter).
I am afraid to, for the same reason I didn't catch a ride in an Exocet along with my son James, because if I do, then I will get all rowdy and want one.
