Picked this car up because my previous car (99 mercury sable) succumbed to frame rot. I only drive a few miles back and forth to work and I'm hoping this can be my dd. Car looks in good shape, interior clean, New tires, undercarriage has very minimal rust. Only thing I noticed is a rattling noise going over bumps. Can't tell if it's from the front or the back end, it almost sounds as if it's coming from the floorboards. Recalls were done as well. It has 139,000 miles on it. Anything I should know?
