Wanted to get a quick opinion before leaping.

I'm buying a car for the first time. I test drove a 2001 Nissan Sentra and loved the way it felt. What does /o/ think?

-2001 Nissan Sentra GXE
-78,000 Miles
-One previous owner
-Excellent Condition
-5-Speed
-Clean Carfax
-$5500

Up until now I've been driving mommy and daddy's SUV, so this will be quite the change.
