Not I, the Z is almost where I want it to be, just a bit more to go. Besides, my Z and a 5th gen are two different animals. The Z is loud, has a fairly harsh ride, gets not so great mileage and is just a blast to drive. The 5th gen is more refined, sedate, definitely more friendly to the driver than my Z.
But when I can get a 5th gen I will, and it wont be staying stock for long. Probably wont go with a big cam so the driveability doesnt suffer but will definitely be going FI.
