Q: Put the $ into it or trade in?

asked by on

I am about to pay $600 for new spark plugs, coils, valve cover & gaskets with a warning that a catalytic converter may need to be changed down the road. Put the $ into it or trade in?

My car has 140000 miles.
My car has an automatic transmission.

As with any vehicle you will need to have maintenance done that will cost money. If you feel the vehicle is worth more as a trade in rather than fixing it is going to come down to other problems with the vehicle, value of the vehicle before and after repairs are done. I can only recommend looking at all options before trading out the vehicle. Just in taxes alone on a new vehicle will be more than fixing the vehicle now.
