Here are a few things to read up
CSC
Master cylinder
Steering lock
Oil consumption
Rear differential bushings
These are known issues with the 370 and most of them likely will burn through your pockets. Rarely does Nissan honor any warranty claims unless you're still under their 3 year warranty then you have a small chance getting anything covered. I'm sure I missed some stuff and other people can chime in, but do some Google searches so you know what to expect.
Good luck and welcome aboard!
