<prompt> Human: I have an 06 Ford Taurus with about 143k miles on it. Ive had this car since 08 when I got it as a graduation gift from my parents. Ive never had a car payment in my life. Well, we pay for my wifes car since we got engaged, but still.Anyway, I just sunk about 650 in it for some repairs because it still runs well. But were trying for kids and need a family vehicle eventually. Also, my wife would like a safer vehicle. She has a 2012 Jetta for the record.I want to wait until the kid comes because who knows when that will be. Could be 9 months. Could be 2 years. But my real question is, for both the present and the future, when to give up on an old car? What makes the most financial sense?Our new car will probably be an SUV or hatchback in the 10k range. We probably wont be able to get the newest safety features, but we should get a decently safe car thats only a few years old right? I dont mind financing it as we should be able to get a 2-3 rate judging by our credit scores and the Jetta refinance we terms we got 1.99 over 3 years with Suntrust.So when to give up on 10 year old car with somewhat high mileage but in decent shape? Repairs will keep mounting and its probably only worth 1500ish total. But it still runs fine as of now.  <response>: 2006 is not an old car
