@Evan: you might wanna look into the Evora S... 350hp supercharged Evora.. it is fast enough to tie or beat the Cayman R, yet it has more comfort and luxury.
Btw the real competitor is the Exige V6 S with the same supercharged V6. More hardcore and it will dance all over the Cayman R.. although it remains to be seem how crazy the pricing will be.
