garyk/nm: Be aware that the Sentra SE-R uses the 2.5L engine IIRC, and there are TWO issue with the design the came up in recent (2000 onward) models.
1. On some production runs, somebody forgot or neglected to use or specify use of "locktite" on the small screws that hold a butterfly valve in place inside the intake runner of the engine. This has lead to the screw coming loose and being ingested by the engine. Much fun results (but not for the owner)
2. The combination of placement of a pre-catalytic converter just down stream of the engine, possible faulty catylist material and valve timing as lead to the pre-cat breaking down on some cars and being aspirated back into the cylinder via the exhaust valve. The pre-cat is a ceramic item and the small pieces/dust does bad BAD things to the oil control rings on the engine. I've read of at least one owner who is on his THIRD engine (fortunatly courtesy of Nissan)
This MAY have been addressed with the 2006 model year

http://www.b15sentra.net/forums/I have a 2006 Sentra, but opted for 1.8 S since it does not have those issues, and the one on the lot had a 5 speed gear box, ABS and side airbags instead of the nasty automatic slush box the SE-R on the lot did , and "sexy" is irrelevant to me (no car even comes close to the sexy-factor of my red '94 Suzuki Intruder).
As for the Saturn, I recall some issue with oil consumption on those engine as well in past years.
50 Shooter, I've shyed away from Hondas and Acuras due to a perception that they're overpriced. Am I wrong on this?
Honda does charge a premium for their name, but overall they are VERY reliable vehicle. My Sentra's predecessor is a '91 Civic HB, and ran for 15 years/150k+miles (hard miles, including some four wheeling fun). The only major issue I had was a fouled cat converter in March, and a few weeks ago it lost an exhaust valve on cyclinder #2 (hence the move to the Sentra). Still runs, just will not pass emissions. I'll 'prolly put it in the garage and replace the head myself and gift it to my neice in a few years.
