I would strongly suggest test driving the Versa you will actually buy....drive it in all lanes....brake in all lanes...see if it tracks and brakes straight...and does not pull.
As far as all of the other issues....apparently, if one just reads this forum alone, there are Versa's with no issues...there are Versa's with one or more issues...and of those issues, most are unexplained and/or dismissed by dealerships.
Take into account as well your personal level of tolerance. After owning three Toyotas, two Hondas, one Infiniti and now an Acura and a new Sentra (which replaced a new and unrepairable Versa) that did not squeak, click, clunk, or rattle, that tracked and braked straight, that did not get tossed about by the wind, with great A/C, working fuel pumps, bright dash lights, defect free TPMS, brake and gas pedals properly spaced that started every time and did not inexplicably lose power while driving...I personally think that in general people should be less tolerant of various issues in a brand new car....if so, manufacturers would have more motivation to make sure that the cars did not have imperfections when they leave the plant.
The Versa is a nice car...when it functions well...however, it seems that it is a crapshoot in terms of finding one that is problem free....and regardless of justification, it is ultimately up to you as to whether or not these issues are issues that you believe you should have to tolerate in a brand new car.
NHTSA.gov has 22 complaints logged already on the 2007 Versa. You may want to review:

.....and also review the feedback in various forums on the web...and then decide.
It is my personal opinion that the Versa seems to have more issues for the specific model than other Nissan models..as well as that of the closest competition.
I personally I think that Nissan made an error with the Versa.....in wanting to deliver a lot for less, "less" won out over consistent quality.
Best wishes with your choice.
