The following excerpt is from an article "State reports find fraud rate of 42% in auto body repairs," published in the Sacramento Bee newspaper in September of 2003. The Bureau of Automotive Repair (BAR), a branch of the California Department of Consumer Affairs, investigates complaints about collision-repair shops in California. "For the past two years, ... consumers have been steered to BAR to determine if their cars had been properly fixed by collision-repair shops across the state.

'This is not a true random inspection but a complaint-driven inspection,' said David McClune, chief of the California Autobody Association. The cars belong to disgruntled drivers, he claimed. 'The results of this study can't be projected upon the industry as whole,' said McClune."
