A little late to reply but back on topic
An honest assessment of the Versa is at best it is a mediocre car. I have owned many cars and currently have five in the family fleet.
High points: Room. Nothing in its class comes close to passenger space. If you routinely haul around three or four people and need a small car, the Versa is great.
In 2007, when I bought my Versa, the car was somewhat competitive. For the money it had some good features many other cars in it's class didn't have like, anti-lock brakes, side airbags, etc. A 2007 Toyota Corolla with the same features was approx $4000 more at the time.
The Versa does not age gracefully. It has a ride like a frozen turd and rattles badly. Many interior parts feel and look cheap. Mine has been in the shop for several odd problems that can be traced to poor quality parts or construction. I am currently renting a 2012 Versa hatchback while my 07 is in the shop being repaired from a rear end collision. Nothing has changed in five years and the 2012 has the same frozen turd ride and rattles. Expect gas mileage 20% worse than other cars in it's class.
If you can pick up a clean Versa that is several thousand less than a comparable Corolla, Focus, or Elantra, it may be worth it.
