After driving it for two days light came back on so I took it back and got charged again telling me it was an oxygen sensor and charging again for diagnostics. Oxygen sensor showed up before they erase the codes according to Colorado Air. Anyway I thought this would fall under the same first diagnosis but it didn't so I got charged again . Awesome people. Just thing that charging twice was disappointing.

I called Collins to see what they could do for me, since I did not get what I paid for and the answer was. No, it's done and nothing I can do for you. A shop like them should at least offer partial refund or something to make a customer happy. They must not care about their customers. Would never go back or recommend anyone else to go either. That's not even to say they over price their service. Good luck everyone and stay safe! God bless you all

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".
