all the plugs look like new,I replaced them when the motor was installed

This Is the same thing that happened with the original motor,at least this one still runs for now,the car Is like new,inside and out,but but I have over $1.500 in It now!book value is $900.00
per KBB I was going to scrap It last time(I was very %^$& at It then),but found the other 86 Aries for the motor,but my car Is too nice to dump
Into a scrap yard,but i'm sure nobody will ever want it,so what should i do?????
