@sharonewing is it paid for? :-) Fix it! it will pay you back every mile you drive it. You will not get anything cheaper than the one you have right now. Car payments are a terrible waste. You will get poked in the eye if you try and sell it damaged. Yo'll never get fair market value and you will lose money. Not good unless you are independently wealthy.
Fix it, drive it and enjoy saving your money for more important things than transportation.
Repair is War on Entropy!
