I now have 25k miles and not one problem. I'm 6'4" and fit comfortably in the Sentra. Much more head room in the Sentra then any other compact car on the market. I drive smooth and easy (the speed limit)and get 28/29city and 36/38highway. I don't think you can find a better car for the money(I paid $15k).
Lots of trunk space. Excellent MPG. great design inside and out.
