I bought my Sentra new in 2003.
It was a great car, but since I live in the north, I found out the first winter that it needed snow tires, and after getting those it was a great winter car.
I live in a town with steep hills so great traction is really important.
Although the car rode a little low, it never got stuck in snow.
The cluster that controls the gauges failed in about the 5th year, and luckily my extended warranty covered it.
I recently traded it for a very low mile 2007 Toyota Corolla and regret it so far.
The Toyota has horrible road noise and handling. I am going to replace the tires and hope that helps.
This is a small car that rides and handles more like a mid-size car, especially with upgraded tires.
