If that car is made like the W107 (from a similar era), the problem may be failed fender seals and the plate/body putty that seals the inner/outer fender and the rocker. My car was completely rust free except in areas where the body seals failed (front bumper mounts, and a previous badly-done accident repair).
CHECK THE BLOWER MOTOR AREA and ALL BODY DRAINS FOR BLOCKAGE. If any is found, run away.
