For my 81st BD I bought myself the above car. It was in perfect condition and had 62,000 mi. I had a Mach I when I was 30 and have always been a Mustang fan. These are my questions. 1) What does s197 stand for? 2) Inside on the console, to the right of the gear shift there is a small pop off cover maybe an inch and a half long by a quarter inch. Can't find it in the book and the mechanic at the Ford Dealer didn't know what it was for. 3) I've only own the car for eight months and a week ago noticed under the hood, just behind the latch there's an 8X4 inch area where the paint has pealed off to the metal. Is this a common issue with the 2005 to 2009 Mustangs.
