silly question

K my dad is selling his car and i really want it. He says if he doesn't sell it in 2 weeks than he'll sell it to me for cheap. What i want to know is if there is an easy and safe way to make it look like there is something wrong with the car to a non mechanic but takes like just two seconds to fix? I know this kinda sounds mean but i want the car so bad.
Thanx

Loosen some wires under the hood. Either that or screw with one of the sensors...

yeah pull some wires on the o2 sensors.. that should cause a cel to come up... messing with sensors usually will cause a cel to come up.. and i'm assuming that's what you want
