I have 4 vehicles been taken them to merchants for oil changes for 4 years don't trust them enough to do mechanical work, all of a sudden at the same time all 4 cars pull to the right brought one back they took it in gave it back and said "your all set sir" meaning it's fixed, drove it down the street still pulled, gave it back put it on the alignment machine they amitted it's out of line, just had new tires and alignment done/w my trusworhy mechanic. they gve me a free alignment, drove down the street it still pulls. all 4 vehicles now pull to the right.district mngr TOM ROWBARKER doesn't return phone calls, several months later all 4 vehicles still pull now all 4 right side tires are worn more than normal! my regular mechanic says so easy to lossen up a bolt the car will start pulling how convenient for merchants to get 4 alignment jobs/w 16 new tires.their bald face liars, that i trusted to take care of my family's cars.
