thanks for the info catso. The car did indeed have quite a rear bumper area rust-out, it didnt look like it was long for being attached to the car. there were three or four other rust spots that had been filled, but looked like they would be trouble again, around the fenders and lower door areas.
I did not notice any frame rot, but I didnt have a lift.
I took it for a spin and noted a loose and mushy steering situation, and there was some kind of scraping/catching problem with the front brakes. not sure if it was a bad rotor or something with the abs? also, the oil lamp flickered at low idle, and the inspection light was on.
not sure how serious that would be.. anyway, I decided against purchasing the car.
