2ndVQ35

Well...they didn't take it back...and I have been driving it for 6000 miles with a freakish first gear wont engage problem that wont reproduce itself at the dealership...well...third visit...Finally - tech took it home and had it happen to him! YAY...New transmission on order under warranty...they offered to do the clutch for parts cost since the tranny is coming out ...

Phew... now that brings me to my next questions...while it is just a parts cost...

A. Car has 36k on it and the clutch feels bad to me - should I buy a clutch now?
B. If I should buy one - should I have them get the nismo? Advandages/disadvantages?
C. Since the car was bought 6000 miles ago and the clutch is kind of weak...do I have any leverage in asking for them to do the clutch for free?

Thanks as always all...
