I took a car to them that was running rough, misfire codes that I couldn't fix. They charged me $625 to remove the intake and then declare the car needed a new engine and that would run over $9,000. Obviously, I declined and picked up the car. Some internet research, a few new tools, and I narrowed it down to a valve. Took it to a local guy and $2,200 later and a head job, it's as good as new. Save your time and money and skip the service department. $625 for nothing and not to recognize the motor as repairable is reason enough to steer clear.
Everyone was nice, so I guess that's something.
