If I sold the Z or were to do it all again I would look at something like an RX7 with a LS(X) or look to pick up a 06+ Z06 in a coulple years (after some depreciation). Having a car that can be brought down to 2600-2700 lbs with the same or greater power potential of our cars would be IMO "the holy grail" of automotive performance.
For the record I will probably never sell my Z.
