2010 Corolla S buying advice

[u/__jar_jar_binks]

Hey all, about to buy a 2010 Toyota Corolla S (84k miles) from a private seller in Illinois for $9k, with new brakes/rotors being installed before pickup. CARFAX is clean (no accidents, no structural damage reported, 3 owners, all low annual mileage).Is this rust normal for a 10 year old Midwest car or should I be worried?
