I had a problem with a rear strut that Groff's had replaced just over a year ago. They checked it out, found that it was defective and replaced it. I was called when the work was done and was told that they heard a minor noise from the other rear strut and were going to replace it was well. This was done timely and at no cost. It may seem like this is what Groff's should have done, but I feel they went out of their way to make sure everything was correct. Groff's probably could have put off replacing the strut since it wasn't a noticeable problem but they took the time to do the right thing. I've always had great service and workmanship at Groff's.
