Yeah, I think the purchase will be largely dictated by noise as much as fun should it ever happen.
Things I am entertaining:
Boxster- cheap and easily available
Maserati 4200 - potentially ruinous but sounds good.
AMG of some kind, as above although maybe less risky.
996 - getting a bit spendy, not the bargains they used to be....
Will probably end up with a boxster, although 4 seats would be useful for occasionally getting both kids in....
