Keeping a Porsche 911 Targa 4S Heritage Edition Reliable in Phoenix
Arizona heat is the hardest test a Porsche will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a 911 Targa 4S Heritage Edition that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for 911 Targa 4S Heritage Edition owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Porsche 911 Targa 4S Heritage Edition, a pre-purchase inspection shows what the paperwork does not.
