We need a good reliable car

hello my name is Steven Cox - my partner David johnson and i  have been together for 32 wonderful years - however starting in 2005 i have had a series of heart attacks and lung failures - after countless weeks in the hospital - my meds were changed along with my diet and exercise. my heart is now working at about 40 % which is a great improvement over 2015 when it was at 15%. We both worked long hard hours to have the things we needed and to provide as much as possible for friends and family members who needed a little help- we almost lost everything in 2005-2006 buy thankfully i was able to renegotiate my home loan terms to under $500. a month payment- and cut back on all spending. I get SS and its not alot but since 2013 it has provided for most of our needs- David in 2008 had a major panic attack that almost killed him and has not been able to work or hold down a job - we have applied for a 3rd time for him to get disability- 4/14/2017. our problem is we have no car- and have to rely on others to get us to our drs. appts, store, pharmacy and anywhere else we may need to go
.i am asking for anyones help in helping us to reach our goal of 3000 to get a good cheap car that we so badly need.
