My wife car

Me and my wife just bought a house. But my wife needs a car. We thought the house was more important so we sunk all our money into a house. We love the house but my wife needs a car so she can keep her job. Other wise she will be fired for not being able to take certain shifts at her job because she has no way to work. I can't always take her because I leave early in the morning for work and get off late at night. Someone will sell us a 2004 Isuzu Rodeo for $ $2,600 as long as we get the money within a week otherwise he wil sell it to someone else. We got $1,400 already thanks to us using our whole tax return. So please help us. I know there are some good people out there. Who knows how it feels to not have a car and have life more difficult because of it.
