I have had my Mustang for almost 3 years now and 69,000 miles on it. When do you folks think the main drive belt needs to be changed? What other safety items should I get checked out? Thanks.

 

100k before you change the belt unless its cracked/shows signs or wear and tear. Brakes, spark plugs, (depending on year- 1 piece or 2), tires if they are still stock, fluid levels, air filter, replace fuel filter, fuel lines, brake lines.
