Really professional and fair. I had a Cadillac with serious driving and emissions problems. I went to one of the big box companies that said they could fix it. After over $800 and still the same problems, they told me to "get a waiver" because it couldn't be fixed. I took it to a transmission place that "fixes check engine lights" and they got me for $1200 and todld me it couldn't be fixed. The state told me to go to Happy Bear because they had a long reputation of 5-star ratings. They fixed it right away-first time and I got my sticker.
