I would maybe consider selling the 2009 Versa HB and buying a newer one with the power windows and locks already installed. You can buy a 2012 Versa HB well below bluebook and with minimal miles from Hertz Rent2Own. I bought my 2010 Versa HB fully loaded with only 21,000 miles for $5000 below bluebook from them. Great car and had it almost three years now. The car was still under factory warranty too.
