<prompt> Human: I just bought my first car in cash, a Mazda 3 I Sport 2010 with 157,000 miles. Upon speaking with USAA about the car, I was informed it was actually worth about 8000 and a quick vin number search confirmed it was worth anywhere from 6,900 for a trade in and 8,300 for a private sale. I am wondering if it would make more sense to keep the car and be happy I got a great deal or sell the car and upgrade to a newer vehicle or one with less miles. My current concerns are that I spent 500 on the title, registration and plates and I would have to pay that all over again for the new car. I havent purchased insurance for it so I could sell the Mazda and just insure the next car.My needs right now are commuting to school which is about 3 miles a day and making the 400 mile trip home on holidays. Im not planning on selling and saving up the extra money I would get from the sale because I will be going into a 60K job in he next year or two and would probably buy another car a year or two into the job.EDIT: I cant do math. I paid 5200 for the car with plates and registration so car value was 4700.Assistant: I just did an edmunds true market value of a 2010 base model 3 sport with 157,000 miles and it has it listed as worth 4200 private party in clean condition. I dont know that you would get much more than you paid with that high of mileage on there. Id just keep it. Those cars are awesome.Human: I also checked the value with KBB and got a similar number. Any idea why vin number checks bring up a much higher number? I used Vehicle History if it matters. Completely agree, fun car to drive, its whipy and light.  <response>: Im not sure if those take into account the high mileage.
