 I bought Sally the Sentra the summer after I graduated high school.  It has been 5 years and I have not had one single complaint!  It gets excellent gas mileage, it is fun to drive, still peppy even with 100,000 miles on it.  There was a recall on it right after I got it, and when it was fixed it got better mileage than the sticker said.  I would keep it forever, we just need something a little roomier.
