Rust, Rust and more rust. Take the front carpets/mats out and remove the wood and check for rust at the fire wall. Lift up the rear seat and check for rust where the control arms bolt to the body. Check for rust in the trunk by the shocks and in front. Also if the car runs and drives drive it and listen for whine from the trans, especially in 2nd gear. Also notice if the speedometer needle goes way down when lifting off the power, sign of trans work needed soon.
