Awful! Run while your car is still in one piece!
I brought my car to Bernie to replace a simple AC hose. (He diagnosed the car as such, as did one other shop). Long story short, he attempted to fix the car 4 times, and each time the car got progressively worse. By the time he was done with my car, I had to pay another shop over $1500 to rebuild my ENTIRE AC system. On top of that, he has been extremely rude during the entire process, even hanging up on me when I called to explain what the other shop told me. That is simply NOT acceptable from a customer service standpoint. If I could give him a negative number of stars as a review, I would. Please save yourself and don't go to him!
