<prompt> Human: I have an opportunity to buy a new vehicle, replacing A: that is company owned that I drive for work, and B: my personal vehicle that is completely paid for. I have medical problems so my company provided vehicle hurts to drive. My personal one is getting on in miles, and fuel economy is terrible. Since my company will pay me mileage, the actual payment and gas will be covered, I just have to cash flow until I get reimbursed. My insurance is pretty minimal, but that would be what I cover myself. My plan is to buy new, drive it til the warranty expires and trade for new again, so its always covered. Would only take 2-3 years to burn up a 60k mile warranty... which is the exact amount of time I would have enough equity in the new one to not lose my principe investment. So basically its going to be a form of high mileage lease. Not to mention I can write off the mileage on my taxes and get an extra bump on my return. I havent spoken to anyone yet that thinks this is a terrible idea. Edit: I guess I should specify this is a new truck replacing two trucks. Trucks hold their value very well, and Ive never had anything but problems with used vehicles. Assistant: Whats stopping you from just using your personal truck as your work truck and taking on the mileage? Youve already said the personal truck can tow, it doesnt hurt your hip, and its not going to put you 20k in the hole for a new car. You still get the mileage. What am I missing? The lacking fuel economy and mileage arent great reasons to buy a brand new truck if it still runs well.Human: Thanks for asking that. Its probably the question Im stuck on. What I keep going to is right now it has 70k on it. No warranty. It still has value but wont in two years of driving like I do. I feel like Im in a zero sum game.  <response>: You take the 0.55 per mile, save it and put it into a savings account. You use it for repairs that are now no longer covered by warranty on your current personal vehicle. Drive it another 2-3 years, then sell it and use the mileage fund to pay for the next car or part. Now youll be in the same position 2-3 years later, with a proper down payment sale of old car mileage payments for a newer car. I still wouldnt get a brand new truck at this point 2-3 years later, but to each their own.
