Ok, I can't figure out a way to word this without seeming angry or slightly judgemental ... read at your own risk I am going to talk to you like I would if you were one of my girlfriends (I am blunt and with out a filter)
HELLOOO you have 3 kids! You need to each have your own car. What would happen if you and the kids were home and one broke his/her arm ... what you gonna call an ambulance to take them to he hospital? And at this point it seems to me that he is going to be resentful of you borrowing the car when you need to grocery shop and run household errands. You are married you should be a TEAM front on decisions that effect the HOUSEHOLD. Going down to one car for a family of 5 is insane and he should not tell you that he is not going to pay for a car that keeps you and your children safe.
My boyfriend and I have a 4month old son and a few months ago his car was parked on the street, someone slammed into it causing his car to be out of commission for 2 months while repairs were made, we rented a replacement car for a month (all we could afford) and he and his friend shared a car for the remaining month because he KNEW with out question that there are two things my son and I CAN NOT be with out ... a car and a phone.
"He feels since he works 40 plus hours a week and pays the bills I should make the sacrifice" That's nice of him to work 40+ hours a week, I beleive you have 3 kids AND part time work YOU NEVER STOP WORKING!!! Does he get THAT?
Plus the family businesses are Cars and Homes, YOU WILL NOT GET A MORTGAGE FOR AT LEAST 5-10 YEARS with a repo on your credit.
1. It doesn't show as voulentary and even if it did all that shows the lender is that you can not make good purchase choices.
2. You will have one heck of a time trying to get another car ... in 2002 I have a voulentary repo (I was 19 and thought I was smarter than my parents) I STILL can not get a car even though I have the money to back it up with out an INSANE down payment.
3. Credit rebuilding to get a house would take YEARS so, if you do not want to buy a house for at least 5 years go for it. just know that it could also effect renting a home or apartment. GOOD LUCK!
In conclusion if this were me ... I would fight TOOTH and NAIL to keep my car, for me it would get to the point of ok then I will walk out and go buh bye if you dont want OUR bills to be paid by US, we both work. Both of your jobs generate money and responsible people.
I will now step off my soapbox and wish you luck.
