Chuck,
The Z is a six speed car. It gives me something to do when I can't lean.
I looked at the BMW , a TT, and a G35 before going with the Z. Both the TT and the BMW were too underpowered to consider. The G felt to much like a family car, and it wasn't available in "Marune". The Z is a touring model with "Nav" and a great sound system.
I see your Crossfire is a rag top... the Rune or Crossfire.... tough choice on a nice day. That is one of the reasons I bought a coupe.
Then again I hear you have more nice days than the Northeast.... not counting the little bit of wind you had last year.
My wife's 300 has a AutoStick / bump shifter. Not much different than when you were a kid, and beat up on the family's ride.
