Sorry to hear about your car. It really depends on what you want & can get Nissan for. For me, I would pass on any of their stuff with the exception of the back up camera mirror. I would shoot for a handful of free services. You can do a lot better with the aftermarket for things like exhaust, suspensions body kits.
