What repair shop doesn't charge you when nothing is wrong? THIS ONE!! I've taken my BMW in twice for different weird alerts showed up. The first time they charged me a fraction of what the guys across the street would have (I know this because I used to go there). The second time I called to see how late they'd be open, they called me by my name (from the caller ID) - love that. They couldn't find anything wrong, after lifting it. And NO CHARGE. I will be back!!
