Congradulation on your new porsche!
I am not a skilful driver, I feel more secure driving fast in my cayman s!
I like the 997 better straightline speed and it feels more intimidating in a fun sort of way----a unique experience!
I think the cayman sounds louder cause the engine is RIGHT BEHIND YOU! You can make it louder by removing the sound deadening cover on the rear compartment---it helps to demist your rear screen during winter!
PS. 997 looks nice in dark colour---in an ideal world you would love to have both cars plus a RS4 for all motoring occasion
