2011 Nissan Sentra or 2010 Toyota Corolla?

I'm looking to buy a car, and the best deals I have are the Nissan Sentra S and the Toyota Corolla LE. I like the Nissan Sentra more than I like the Corolla, because I feel it's built better. I feel the interior of the Sentra is better quality than the Corolla (the Corolla is really cheap as far as the interior goes). Also, the Sentra is right now about $1,000 less than the Corolla. However, the Corolla right now comes with 2 year maintenance and the dealership I'm working with has tires for life, though I'm not quite sure I'll be able to take advantage of that, given that I'm a student and will be living in a completely different geographic area most times out of the year, and the tires for life is only good for cars that are maintained at that same dealership. Both cars come with all the exact same things. Which one should I go with? And please try to give details! Don't just say, "Corolla (or Sentra) sucks...I really want to make an informed decision here!
