I believe Shawn, the owner of Proformance, is honest and knows what he's doing. Those are probably…read morethe two most important things when it comes to picking a mechanic. But: One time I needed an engine installed, so I got an estimate from Shawn and had him do the job. The final bill was exactly double the estimate! More recently, I needed a VIN verification on a trailer. The office manager took one look at the data plate and refused to verify the VIN (which also had supporting paperwork), insisting that "it's not a VIN" and that I needed to have the highway patrol issue a VIN. This was said with some hostility, as if I was trying to get away with something or make her an accomplice to a crime. So I went across town to Air Care Colorado, which cost me extra time and money, and there they didn't even blink, they just did the verification, and I now have the title to the trailer with the totally-legitimate 6-digit VIN. I should also mention that Proformance giving discounts for 5-star reviews is a violation of Yelp's review policy; it's considered "Compensated Activity".

Well it's refreshing to know someone who can work on all kinds of vehicles, because he knows his stuff, and he is a good man too. How many men do you know who have their son's working for them? Most want to get as far a way from their dad as they can, but not Kevin's sons. Kevin has taught them a very valuable skill that will be needed for years to come, but more importantly he is teaching them how to be a man. They do great work, and let's face, everywhere you go, will be expensive. That is just reality of today's world. Everything is expensive, but rest assured, when anyone works on your vehicle, you will get what you pay for and Kevin is not out to short change you, but he will shoot you straight. I take all my vehicles to Kevin. They will be done right.

After they completed my engine repairs my serpentine belt began to squeal and my AC was drained. I've had them replace the belt 3 different times since the repairs, and it's continued to squeak each time. When I called in today to remind them that they never refilled my AC and that I was on my way in so they could make it right, Stuart became angry and began to yell at me to which I responded by hanging up immediately. I'd sooner pay someone to fix your mistakes than ever bring my vehicle back to Stuart's shop, which is what I'm now doing. In March my girlfriend brought her 4Runner in cause she was having what we thought was an alternator issue. She was told after they did a diagnostic it was in fact just her battery. When she went to interstate to get a new battery they also did a diagnostic and told her it's the alternator not the battery. The man at interstate battery also said that whoever had done the initial diagnostic wasn't the brightest bulb on the tree. You literally plug it in and the computer tells you what the issue is... Unless you like wasting time and money, or being yelled at for asking someone to fix something they broke, this is not the garage for you. Stuart should remain in the garage, and not be allowed to talk to customers because he has the communication skills of a 6 year old, no wonder he has his mom answering the phone for him. Sincerely, someone who will never return to garage 9
