@Bailey28 - what was the $2100 expense for that contributed to the not reliable vehicle? We have all been there, the costs at shop and parts are crazy these days. At $2100 that is 4-5 months of car payment except the car payment will continue and will also need maintenance, parts. I just did $900 for a serpentine tensioner in a 252k '08 CRV. I did about $1000 for a CV axle and transmission mount in a 195k '10 Forte for my kids. I trust the cars and so do my kids. Do they want new and shiny, my son does, my daughter wants hers forever. My son has a good job, makes what I do after 34 years in management at my job. He has a lot of loans from Physicians Assistant school as does his wife from her teaching degree. Both working but the loans are a large hindrance. My son and his wife (at the time fiancé) lived with us for 3 years in his bedroom and having basement to themselves. They wanted their own place but him not working made that kind of impossible. My wife and I explained with both (and my daughter) why they should live with us until they get the jobs. My wife and I enabled them to focus on school, not worry about monthly expenses. They long ago saw the wisdom of appreciating the assistance and guidance. My daughter is currently living home doing her clinical rotations. When she does have "free" time with a day off she works as a substitute teacher to make some money. My house expenses don't change that much for the opportunity it provides for them.
My wife and I have shared all of our stuff. Life experiences, values, our income and expenses and what our retirement funds have from starting early. Perfect, nope, hardly, but when you can show your kids the monthly income, after taxes and retirement savings it gives them a good view of life. My son had to argue with his wife over many money things, wants, needs, expectations, budgets but they are more or less in alignment. They got a dog, cute but bad idea IMO. I know she wants kids sooner than later. We can advise to wait a couple years but they will need to make their own life choices then. He is 25, his wife is 24. They now live 8 hours away and their apartment rent is 1/2 what it would be here in NY. Their focus is hitting loans hard while saving some. Juggle between early hardre savings and paying interest on loans.
Maybe as others have said, have your daughter start giving you $400-500/ month now. Invest in a CD or higher yield savings, maybe a Roth IRA. If she stops giving you monthly $$, take the keys or make it undriveable. Explain how the vehicle repossession scenario works. If she can't afford that every month while living free, she obviously can't when on her own. Maybe add for any other expenses you cover. Of course at the end you can give her all those funds at what time you feel that is good.
She has access to trucks/trailers. She could also rent a Uhaul or Home Depot truck for $50 and get all the stuff she needs. $50 bucks and someone there might pick up or deliver it for her. Small trailers are cheap as is a tow hitch. Don't forget to factor the insurance costs of new vehicle you can add that difference form current to new to the payment.
My dad made my kids and my nephews a deal when they started working in high school. He would match whatever money they made for that year up to the ROTH IRA contribution limit for that year ($5500) but it had to get invested. He wanted them to enjoy the money they made but also see what investing can do. Those $5500 have I think quadrupled in 10 years since markets did very well with what it was invested in.
My wife and I will continue to spoil our kids but in ways to help them succeed while they appreciate all of it as long as it fits our budget and planning. My parents did the same by taking us on vacation that they knew we wouldn't or couldn't afford. They helped with some house expenses and repairs. They helped with additional college funding to help offset. Their words, "we would rather spend money now so we can enjoy time with you and the grandkids then have you inherit it all later". My parents did a combination of mine and wife's birthday, anniversary and Christmas. We got upgraded insulation (did it with dad and I crawling in attic) and had central air installed for 15 years of future comfort. Dad has passed, mom is comfortable for expenses at 89. They said we need to do the same and instill the same values in the kids for the grandkids some day. Currently that covers going to dinner with them, keeping older cars working and filling them up when they are home.
