I'm curious if it's possible to get just a drivetrain extended warranty?? And is it considerably cheaper? I'm just starting to look cause my drivetrain is up in november. Still way under 60,000 mi. But with two new tranny's in the 6 months i've owned the Z, i'm kinda afraid not to have at least a drivetrain on it. Thanks! Is a Nissan extended the best/least hassle way to go??
