<prompt> Human: My 2004 Mazda 3 needs a Heater Core replacement that would cost around 1,020 7.5 hours of labor, plus parts, new coolant, and tax. My car has just over 144 K miles and runs pretty well if we look past the heater core. Apart from this upcoming repair, I spent close to 500 back in April for an alternatorbattery repair that included towing, and about 350-400 in January for 2 new tires. My wife has been suggesting we trade in my car and get another for a few years now. Im hesitant because having another monthly payment would put us in a tight spot. The Mazda is paid off and has a Kelley Blue Book value of about 2,400. It would make sense to me to get another car if the repair cost was greater than the value of the Mazda or a years worth of payments on a new vehicle. No real sentimental value in the car. We have about 3,000 in savings at the moment. The repair would take a good chunk of that. In my wifes words, She would hate to lower our savings so much for an old car. Any suggestions? Im new to this sub so if I left out any important details, please let me know. Thanks!  <response>: Every car needs new tires, youll eventually need new ones even if you buy a brand new car.
