 I purchased my 2005 Sentra SE back in 2008, and the best decision I made was to get an extended warranty. Things break on this car that just shouldn't for the age and miles. My head gasket went out at 38K, my motor mounts all went out at 82K. I've had sensors randomly fail, causing the car to stall on the highway. Overall, I'm at the point where I'm just expecting it to break again at any time. If I could afford a new car, this thing would be gone in a heartbeat. It's a money pit, pure and simple, and the nightmare doesn't appear to be ending any time soon.
