Close to pulling the trigger... any specifics to watch for??

Look for: the bottoms of the rear quarter panels rusted out along with the panel behind it called the trunk drop off, Rust in the rear wheelwell lips, rust In the bottom rear of the front fenders (called the dogleg), Rust in the bottom of the cowl underneath the dash where the fresh air vents are located, rust in the front floors around gas pedal and frame rails.
