This is one of the most common decisions vehicle owners face, and the answer almost always comes down to a few key questions you can work through in about five minutes:
Now run the math: (Running value minus repair cost) versus (EZ Cash Cars as-is offer). If the first number is significantly higher and the car is reliable enough to justify continued ownership, repairing may be sensible. If the numbers are close, or if the repair cost is more than half the running value, selling to EZ Cash Cars is almost certainly the wiser choice.
Add in the soft factors: How many miles are on the car? Has it had recurring problems? Are more repairs likely to follow this one? How much stress is this vehicle causing you? These qualitative factors often tip the balance further toward selling when the financial math is already close.
