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.

Generally I come on here to vent and eviscerate some shady merchant that I'd like to see go down in…read moreflames. This is not the case with Collins Muffler. Here is why, these guys are HONEST mechanics not interested in ripping people off. I know, you may find it hard to believe. Finding an honest mechanic is like finding an honest spouse or business partner, once you've got them, you never want to let them go! I was in there this afternoon after having troubles with one of my vehicles, certain that I needed at least a new starter and possibly more. Not the case, upon their diagnostic check they found there was an issue with a sensor, they reset it, re-diagnosed to be certain, tested it and everything was gravy. The best part was they didn't charge me a dime! Nothing, nada, zilch! Not even for the diagnosis which they initially quoted at $99.00 and I had agreed to pay. Even better than that, I was in and out in less than 30 minutes. If you haven't found your honest mechanic in this life, fret not, hope is alive, for now you have! These guys are the real deal and have gained a customer for life.

I have been going to Aptitude Auto for almost two years and would highly recommend Juan and Isaiah…read moreto anyone looking for great mechanics. I have felt taken advantage of many times using other auto repair places, but never at Aptitude Auto. They make the effort to explain exactly what is wrong and have shown me the bad parts to back up their work. This week I brought my car in because the brakes were squeaking. Juan told me what he could do to resolve the noise, but made sure I knew that I was safe without the repairs as well. It is rare to encounter such an honest mechanic- people who would rather be honest than just make some easy money. Thank you, Aptitude Auto!! You've got lifelong customers because of your fantastic service.

I had a great experience with Ryan! I gave him a brief description of what problems I was…read moreexperiencing, and after a diagnosis, he described the issue, solution, and cost in layman's terms that made perfect sense to me. My car was repaired and I am thrilled with the results! The cost was very affordable too! These guys are renowned for high performance upgrades/tuning, which may make you think the service will cost a lot, but it doesn't cost a lot! These guys know cars! I'm very satisfied and will return for future service.

Ryan called me at least once a week to update me on the progress as well as every time they ran into an issue with poor backyard maintenance practices. I have 1,100 miles on the new engine now without a single problem. I can't wait to see what these guys can do with a tune once the engine is broke in. I would recommend Ryan and the guys at Funk E Built to anyone looking to make their daily driver a little more fun to drive!
