They worked on my e39 M5 with the dreaded "Trifecta" ABS lights illuminated. This issue can be very difficult to diagnose and to figure out what the fix it is. Really need a shop like this, that has the software available to help diagnose and work through this difficult issue. Needless to say, the technician needs to be very skilled and patient, which David at the Woodbury location is! Alex does a nice job communicating with the owner while the car is being worked on, which is very much appreciated. Unfortunately for me, this project was very expensive, because the parts were costly, but Alex was very transparent explaining dollars and cents. I believe to run a shop like this, pay the tech's well and have the best equipment, we need to be realistic about the dollars we are spending here. Don't expect a bargain, but expect a fair price for what your getting. We want them to stay in business, because they do a great job and want them to succeed, so we don't have to depend on the Dealer!! Thank you Alex and David.
