dont worry too much about the milage, ask if the timing belt has been changed, when it was last serviced, EJ9 are pretty safe regardless of milage, make sure it runs and drives ok as some have rear bushes that need replaces, you may hear them knock or bang a little
make sure the engine isnt smokey, or the gasket leaking, the gearbox is fine and no noise or grinding etc, check the brakes, check the oil level in the engine etc too
rear arches can rust on these and can be expensive to fix so make sure there ok or saveable
Front slam panel when you open the bonnet, loads get super rusty make sure it isnt
rear open the boot and look at the panel just above where the rear bumper is held in, again look for rust
think thats about it except making sure all electrics etc work, wiring is ok etc, make sure its not had panels changed unless you were told of them before, check the clutch
HPI check it incase its a cat c or d etc
good luck mate
