Adding the review already written, Robert Stang posted all the other positive commentary on here himself. As a local business owner in Broomfield, its disappointing to write this review. I own over 25 vehicles, between large trucks and smaller vans. While out of town, one of my vehicles was taken into Stang Automotive for engine light diagnosis. Robert's team correctly diagnosed the problem to be a worn out distributor gear. However, he wanted to charge us over $700 for the diagnosis and repair. I took the van out of his shop quickly and took it to my regular shop (Louisville Tire who I've worked with for over 10 years) to have the gear replaced for $266 including diagnosis. When I took my vehicle, Robert demanded I pay him $176 in diagnosis fees, called the police after I took my vehicle out of his shop as quick as I could and stated that this is how they normally do business. They must be preying on people who are clueless on vehicle repair and upkeep. BTW, this is on a Chevy 350 engine, probably the most common engine Chevy ever built. I did try to reason with the guy and explain my position...he just wanted to continue on and on about how we signed for diagnosis fees...I'm still contemplating it...but to me it smells pretty fishy. Also the quote we received over the phone was $636 and the quote I received in person was well over $700...Robert tried to explain some BS about overestimating. Save yourself and go with a shop that charges book rates and does not ask for an open checkbook.
