Timing chain guides. Chances are they are making some noise (with 140k on it). Timing chains are a pretty expensive job to do, it will sound kinda like a rattling spray can upon startup. You could remove the upper guide with no ill effects (to get rid of the noise). Supposodly, the chain system is supposed to last the life of the car.
Other general things to watch out for when buying a car:Before you start it up/take it out, pop the hood and feel to make sure the dude didn't have the car running and all warmed up before hand. In most cases, cars run better when they are warm, so some people do this to make the car seem better than it is. If it is his daily, this might be unavoidable, (as in, it will be warm, but he didn't do it intentionally). If he seems like a shady dude, ask if you can come back and start it up after it has been cold.
Have someone look at the motor when you are starting the car. If the motor shakes excessively upon startup, it probably means bad motor mounts.
If possible, also see if someone can stand at the back and check for blue smoke upon startup. This would mean that it is burning oil (either leaking head gasket, or leaky valves, whatever. If it blows blue smoke while you are driving, it means worn piston rings).
If the car has HICAS (Nissan's 4 wheel steering) it has a limited slip differential. Another way to check this is to see if the diff cover has an orange sticker on it.
Don't be afraid to crawl under the car and check for rust anywhere and everywhere (floorboards and everything). Good luck man!
