Don't trust this dealer!
My husband took his Chevy Silverado to Zimbrick Chevrolet in Sun Prairie last week to have a check engine light looked at. They inspected the truck and presented him with a $1700 estimate. One item needing immediate attention, according to the mechanic, was the front brakes. Apparently, the pads had "no life left in them" and the rotors were "shot." Due to the long list and the expense, he elected to think on it and do what work he could himself. He had replaced the brakes on our cars many times, so bought what he needed and got to work taking everything apart to replace the brakes. Imagine his surprise to discover existing pads with less than 50% wear and rotaries as smooth as glass. He put everything back together and returned the new brakes to the store. Needless to say, we won't be going back to Zimbrick Chevrolet. We're angry and disappointed to be nearly cheated by this unscrupulous dealer.
Lesson learned: take your vehicle to a mechanic you trust (preferably one who cares about having a life-long customer), get a second opinion, or do the work yourself whenever possible.
