I decided to try Mufflerman as I have had very good service in the past. They have always showed me what they were going to fix and have always been fair with their prices. The manager had a mechanic named Jason look at the car. He took a short test drive and was the only one to put the car on a hoist. In a very short time, he showed us our car on the hoist and pointed out exactly what was making the noise. It is a small transfer box below the steering column that is problematic in GM cars but never a safety concern. He said they could fix it but in a couple years it would be making the same noise again. Jason said it was a love car, a safe car, and to drive it with confidence. There was no charge and we could not have been happier. We will continue to take all of our vehicles to the Mufflerman and want to let you know all that word of mouth travels a long way.
