I used to live RIGHT next door to the O'rielly home base in Springfield, Missouri. Convenience wasn't enough...their parts declined in quality so significantly that I would drive miles to Autozone or preferably, 40 miles to a Carquest. Really, that bad.
My '96 Neon craps an O'rielly's crank sensor once a year. Cam sensors are a bi-annual affair. I've gotten to the point where I bought one from a dealer out of frustration...and no more problems.
O'reilly's sells ****. I don't buy anything from them and didn't when they were literally my neighbor. It's the Wal-mart of Autoparts.
