Mine has 170,000+ miles on it. It has taken me across the U.S., up and down mountains, across snowy rural roads, through narrow city streets... everywhere! Paint is peeling off, visors torn. What can you expect. It's an older car. I had to replace the alternator, had some brake work done. Transmission fluid leak gave me a big scare but it was only a $300 repair for that. AC doesn't work anymore (in the northwest though, it's usually fine). We'll get a new car eventually... we are waiting for this one die. But the Sentra keeps on going. We might go another year with it.
Wonderful gas mileage (35mpg or more), comfortable seats, reliable, easy to park, reliable starting, roomy trunk, cruise control.
Age related wear and tear. Nothing unusual or overly burdensome considering the great amount of use I've gotten out of it. I love my Nissan Sentra!
