i to bought a money pit ... i feel your pain. but as others have said , it's your fault for not properly looking the car over just as i didn't. trusting the person that is trying to sell you a car is your first mistake.
i bought mine on a rainy cold december night , so outside of listening to the motor , i didn't look the car over an took the owners word on what he thought was all it needed ... yeah right. he brought the car on a trailer because it had no brakes. he told me previously it just needed brakes and rotors, and had a fuel leak. that was it. all he thought it needed to be on the road.
when he got there the battery was dead.
he said the battery was good it's just been setting for awhile...lie number 1 ... the battery would not hold a charge. first $100 went to a new battery.
put new brakes and rotors on he already put new brake lines all the way around. the entire underneath was a rusty mess. the brake lines rusted apart.
found the fuel leak. the fuel feed line was squirting gas. it was so rusted it was beyond repair. when trying to take the line off the other two , return and evap , snapped in half. dealer ONLY items about ...............................$460.
