be sure to check for rust on these cars, they will rust in a day
also, the fuel tank, make sure it sits in front of the rear bumper as these cars came from the factory with the fuel tank extruding from the rear of the car, any impact over 15kmh and that baby will blow up on you.
also check the hubs, for the wheels, as r32 sedans are notorious for rust, the hub can rust also straight thru to th core, in lamens terms, wheels are prone to come off at speeds of 120/km/h an hour
r32 4 doors also have the foolish positioning of it's ECU, right next to the outlet manifold, so if it gets too hot (and believe me, the r32 sedan radiator won't work after 120xxxkms) the manifold just gets too hot and melts the ECU to a thick goo
aside from these minor quibbles, they are a great car, and yeah, as the guys says just change a few hoses and you'll be sweet!
