I make those drives several times per month. There's only so much you can put into a beater and push it.
Breakdowns cost time and sometimes jobs and money lost. I have to know when I drive 600 miles, that I won't break down.
Hmm new vehicle never break down? Interesting.
Interest rates are high so don't take out a loan. If your job pays well enough you shouldn't have to. Drive am old truck put payment money in savings for break downs each month then pay for the new truck cash out of the same account in a year and a half maybe 2.
If your truck is required and you wear it out so fast that should be a business expenses figured in and taken out of your check like taxes. Or at the least subtracted along with fuel tools and other things you need to do your job off your income.
Once that's is subtracted your not making as much as you thought. Maybe you would be better off making less at a job that doesn't require so much expense.
I went through this process trying to decide if it was worth the pay cuts and reduction in benefits to take a job close to home. It's humbling to pay attention and see how much money I was actually spending and the wast/useless money that goes along with traveling for work. Just what I spend on fast food and convenient store drinks and snacks was mind blowing.
I'm 43 never bought a new vehicle had a couple a year old though. Currently my every day driver is 27 years old. Two of your payments pays for about all my vehicles expenses in a years. That includes things like tires and oil changes that your new truck will need on top of your payments. I live 127 miles from work so do some driving each year.
It's just a different way of looking and doing things. One of my year old trucks left me broke down more than my 27 year old truck. Also if I get sick, laid off or otherwise reduced income or no income coming in I don't have a big payment over my head. I'm not saying your method is wrong just pointing out there are other ways of doing things and why I prefer them. Years a new truck would be nice, more comfortable, and look nicer. But it won't build my net income any more than my old truck infact it will cost me more. The added comfort is not worth the cost to me let alone the piece of mind knowing if I can't work I don't have payment I have to make. Not having payments and paying interest allows me to save and invest more. That is true reliability to me. I'm retiring one month after my 57th birthday July first 2036. And I will have enough saved and invested to be comfortable and secure. See putting that 10k a year more your paying on that truck in investments will pay off big time vs making bankers rich. I don't like debt because debt ito me is slavery. I still have some debt but have moved from debt slave to indentured servant and soon will be a free man.
