<prompt> Human: My boyfriends friend is selling a Ford Taurus with 70k miles. Im not sure what year it is maybe late 90s, early 2000s, but my boyfriend says that it is a good quality car. Hes an auto tech and has done some work on it, so I trust him totally in that regard.The guy is asking for 2000. He agreed to a 600 down payment and 200 a month. To me, it is a good deal for someone who needs a car.But, we dont. In fact, I have a 2015 Buick Verano that Im making payments on. This was my biggest financial mistake but Im dealing with it. Ive had it for 13 months and it has 23,000 miles already. Its underwater, so I dont think I really have any options other than just pay it off.My boyfriend wants us to use the Taurus for our out of town trips to slow down the amount of mileage racked up on my car, by the way. I dont know if this is really effective?Anyways, my boyfriend has a 94 Toyota 4Runner that he primarily uses. He also has a Bronco and a Cobra Mustang, but neither are running. His plan is to get them going and keep them. He said that he wants to sell the 4Runner and the Taurus eventually, so we could use that money for other things, like a wedding, down payment for house, etc.I dont know, I just dont think we need this car.I am building up my emergency fund and it is at 1200. I really dont want to dip into it. When we were talking about it, I said for him to let me think about it, and if we decided to buy the Taurus, Id give half of the down payment and hed make the monthlys. It is doable, by all means, but I guess Im just needing some advice as to whether or not this is an advisable move.Thanks for any advice.  <response>: Project cars are a hobby and should be planned for with that in mind. It sounds like this would not be a hobby car, but would instead by an alternate form of transportation. The main thing to keep in mind is that if you are going to drive it then it needs to pass inspection, be registered with your state and be insured. Because of that it may not be worth it. Youll also want to consider gas mileage differences between the two cars.If you figure out the true cost of maintaining another vehicle and then estimate how much you are saving by putting miles on the Tuarus instead of the Verano Id be surprised if it was a net gain. But it might be worth it to run through the numbers just to prove to yourself and to your boyfriend that his plan wouldnt necessarily be a good idea.You might instead consider using some of that extra money to get out from under that Verano loan. Once you are no longer underwater you will have the option of selling the car and getting something more affordable.
