I’ve been a government fleet mechanic for 25 (+) years. The only time you should use carquest, advanced, autozone, etc is when you are buying parts for a car you don’t plan to keep. Napa is very reliable and trustworthy eventhough you’ll find their prices are a bit higher - there is a reason why they have been around longer then the latest chain/7-11 parts stores. Factory parts are often the best route to go if you want to pay their prices - rediculous. Remeber, there is always some geeky little crackhead at the dealership just waiting to soak up your money.
